and the story begins with an assassination mission. ifirst met isaac gilmore in 2020. he's a former navy seal, who later became second—in—command of a private us military firm called spear operations group. i was surprised isaac agreed to speak to me because at the time, human rights lawyers were trying to prosecute spear for war crimes. one of the reasons that i agreed to participate in this and be part of this documentary is to be very clear about what we're doing and why. this isn't, you know, innocent until proven guilty. it's war. how did you get involved with the operation in yemen? so ultimately, i met abraham, abraham golan, who's a brother and a friend. abraham developed a relationship with mohammed dahlan and that was our path through to the uae government. we met with the appropriate bodies within the uae government. the pitch was to put pressure on isis and al-qaeda in the state of yemen and make sure that it didn't become another chaotic hub of terrorist activity, especially with the proximity to the horn of africa. in 2015, yemen was gripped by fighting on several fronts. a group called the houthis had taken over the capital, sana'a. they also briefly held aden, before a saudi/uae—led coalition — backed by the us and the uk — recaptured the city. al-qaeda had long been a presence in the south and were now gaining territory. the us feared they might plan terrorist operations beyond yemen's borders. the uae took over security for southern yemen and became the us�*s main counterterrorism ally in the region. that was the circumstances that set the stage for us to be involved in yemen in the first place. we had had the sign—off, simply a handshake, and then we had to manage the business side of it. if we were going to target somebody that was on this list, then we made sure, in our minds, that we're not going to go out and murder somebody because this guy doesn't like that guy. we would do our own due diligence. who gave you the targets? we received the target intelligence from the uae government. how did you receive them? in intelligence packets. cards? cards. and one of them was ansaf mayo? yes. the initial operation was to go after the head of the snake, so to speak, and so it was targeting the al—islah leader. al—islah is the yemeni branch of the muslim brotherhood. three years later, when the uae's drone footage was leaked to the international media, ansaf found out that spear had been hired to kill him. ansaf fled to yemen after the attack and now lives in exile in saudi arabia. on ansaf mayo in particular, what was it that made you decide that he is a terrorist? well, there's a couple of things. one, we already know that he was being financed by the muslim brotherhood, and i can tie it all together... but the muslim brotherhood aren't... they're not a terrorist organisation. yeah, they are. the united states government doesn't believe the muslim brotherhood is a terrorist organisation. yeah, they did. at one point, they did. yes, they did. ansaf�*s party, al—islah, or the reform party, is one of the biggest political organisations in yemen. its policies are inspired by the muslim brotherhood, a popular international islamist movement. the muslim brotherhood is banned in several countries, including the uae, where their political activism and support for elections is seen as a threat to the rule of the royal family. but the us has never classified the muslim brotherhood as a terrorist organisation. if your handlers, the uae, said they are definitely terrorists, you had to trust that? yeah, absolutely. it's how it works. the mercenaries will talk about their attempt to kill ansaf mayo because their cover was blown, but they're still guarded about the rest of their list. so tell me about one of the other targets you pursued, other than mayo. i'm not going to mention any names. yeah. 0k. yeah. so, we had another target. all right, this one was kind of interesting. now, this guy was in a walled compound. it was a three—storey house. not very big, but three storeys. guys were asleep, but as soon as we started coming in, they heard the gunshots, everybody got out of bed. and we went in and executed the targets. it was a fair fight. 0k? the story of assassinations first came to my attention while i was documenting human rights abuses in yemen. hey! how are you? baraa shiban is a yemeni caseworker with reprieve�*s investigative team. what you see here is basically tens and tens of assassinations. the team has been compiling a list of assassinations in southern yemen. between 2015 and 2018, they've counted 102. they've all followed the same pattern, placing ied bombs on doors or on cars, and then someone comes after and starts shooting the individual. if you see, then, here, you see a surge in assassinations that are happening throughout 2016. this happens after the arrival of spear into yemen. 25 of these assassinations took place during the months that dale and isaac were in yemen. they said they assassinated a person with all of his bodyguards? yeah. this fits in. one of the names on baraa's list is ahmed al—idrisi. he was assassinated the day after spear�*s attempt on ansaf mayo. ahmed al—idrisi had his security detail around him all the time. what we understood is there was an assault that killed him and everyone around him. the details of this assassination match what dale told us about the target he refused to name. isaac and dale told me that they'd made visits to the port because they were surveilling someone there. so it fits the description, fits the date. ahmed al—idrisi was a leader of one of the yemeni forces that helped drive out the houthis. at the time of his death, his group had control of the port in aden and refused to hand it over to the uae—backed forces. aden�*s port is a key strategic asset. uae—backed forces took it over immediately after idrisi's assassination. were you involved in the assassination of ahmed al—idrisi, which happened on december 31st, 2015? no. reprieve was one of two human rights organisations that investigated the assassination. both told us they now believe spear were behind it, as do other sources. how many targets were you given? um...over 40. yeah. and how many targets did you execute? not answering. by early 2016, dale and isaac's time with spear was coming to an end. i left spear and came back to the us. do you know if spear is still active now in yemen? no. we asked the us department of defense and the state department to talk to us about spear, but they declined. siren wails throughout 2016, assassinations continued to dominate the local news in aden. at the beginning, when those assassinations were carried out, people kept saying, "this is operations done by isis," and so on. it was not until 2018 when we started to pinpoint that actually, this is part of a systematic targeting policy. when you don't have a unified definition about who is a terrorist, you have this chaotic situation. these are extrajudicial killings, and the most important thing is that it's still happening until today. so, after we started to look closely into evidence of... reprieve has obtained what they believe is a financial statement from the uae�*s foreign ministry. it states how money described as aid for yemen has really been spent. that shows here quarterly payments being paid to spear operations group. and this is the amount in saudi riyals. mm—hm. this comes to close to $17 million. we know that spear were there at 2015. this is 2020. what have they been doing there for the last five years? i think that's the main question. what were they doing? to answer that, you'd need to have been inside the uae bases in yemen where spear operated. i found a whistle—blower who was there. this man is a senior yemeni officer from aden who worked directly with the uae. he's asked us to conceal his identity i asked spear�*s i asked spear�*s founder, abraham golan, whether his mercenaries had trained emiratis in assassination techniques, but he didn't respond. in 2017, the uae set up the southern transitional council, or stc, in yemen. one of its roles was to run security in the south. its forces included an elite counterterrorism unit. i met the head of the stc, aidarus al—zoubaidi. he's one of the most powerful figures in yemen's government and works closely with the uae. off—camera, zoubaidi's media adviser intervened. zoubaidi denies that the uae is sponsoring assassinations off—camera, zoubaidi's media adviser intervened. zoubaidi denies that the uae is sponsoring assassinations of its political enemies in yemen, but after months of trying, i've managed to obtain a uae kill list. it's from 2018 and is seven pages long. it was leaked by a source who was working with the emiratis and was horrified by the names he saw on the list. it includes this woman, huda al—sarari. huda's in geneva to receive an award for her work investigating the uae�*s human rights abuses in yemen. in the end, it wasn't huda who was attacked. it was her son. he was 18. eyewitnesses told the prosecutor that they recognised the gunman as a member of a counterterrorism unit funded by the uae, but nobody was charged. huda now lives in exile. the yemeni officer who witnessed the uae�*s counterterrorism operations had a further allegation about the men hired to kill. the whistle—blowerjust sent me this document that has a list of names. these are all guys that worked with isis or al-qaeda in yemen. he said most of the 11 men on the list had been serving sentences for terrorism. we were unable to verify all of them, but further evidence has emerged. this is nasser al—shibah. once a high—ranking al-qaeda operative, he was jailed for terrorism, but later released. a yemeni government minister who'd investigated the case told us shibah was a known suspect in the attack on the uss cole, which killed 17 american sailors. despite this, the uae recruited him to command one of the military units they're backing. he's pictured here with the head of the stc. multiple sources have confirmed shibah is working with the uae. the yemeni government minister who'd investigated the case told us he had informed the us authorities of shibah�*s suspected involvement in al-qaeda's attack on the uss cole and his current role. we put our evidence to the us state department and the department of defense, who declined to comment. peace is still out of reach in yemen. the houthis maintain their grip on the north of the country. their attacks on red sea shipping, which they say are to support the palestinians in gaza, have broadened the conflict. the uae continues to control the security apparatus in the south. despite the evidence that the uae is pursuing its own agenda, undermining stability and making it harder for the yemeni government to return, the uae is still a key ally for the usa. we put a series of questions about spear operations group to the cia. a spokesman said: "the idea that the cia signed off on such activity is false." us laws covering mercenary activity are unclear. no—one from spear has been prosecuted. ok, so i guess, you know, the last time we met was, how long ago, three years ago? yes, february of 2020. you know, did you feel like the operation you took part of was legal? yes. is that because there was some sort of nod from washington? no, it's because we were in line with the us�*s mission in the region and we were participating with an ally of the us. one thing we discussed last time is the kill list. one of the names that was on the list that i've seen is huda sarari, who's a female, a human rights lawyer. not on my list. so the list you have is something different. i would absolutely remember if that name was on the list. to date, spear have not been prosecuted for their role in the uae�*s assassination programme, and the families of victims of the assassinations in southern yemen have yet to receive justice. hello there. low pressure has been dominating our weather picture this weekend. and on saturday, we had widespread showers around, the vast majority of them coming through as rain. we did see some snow return to parts of cumbria and also some snowfall from somerset through the west midlands and into parts of wales as well. quite localised snowfall, but a covering in places. cold air, then, firmly in place at the moment, with our area of low pressure spiralling around, with further showers gradually moving their way northwards for the time being. again, the vast majority of these are coming through as rain. a little bit of sleet or snow mixed in across some of the higher parts of dumfries and galloway. and over the next few hours, we'll also see a bit of snow across higher parts of the grampians. otherwise, any showers will come through as rain. it will then get cold with clearing skies across wales, the middle and southern county of england, lowest temperatures about —2, so some frost and a few icy stretches to watch out for. sunday morning, few mist and fog patches around as well. by and large, though, a decent kind of day coming up on sunday. there will be some high cloud affecting eastern parts of both scotland and england. the best of the sunshine will be further west, withjust one or two showers running through across parts of western scotland, northern ireland, wales and the south—west of england. but even here, the showers will be pretty well spaced, so you've got a decent chance of having a dry day. through sunday evening and sunday nighttime, we'll start to see the next weather system approaching, and that will be bringing more rain our way into monday. so the rain making inroads in across parts of southwest england and wales pretty quickly monday morning. after a dry and bright start in northern ireland, it turns wetter through monday afternoon. we hang on to some brighter weather for scotland and northeast england, that's where the best of the sunny spells will be. temperatures continue to be a little bit below average for this time of the year, with highs between 9—11 celsius. deeper into next week, areas of low pressure in the atlantic will continue to threaten outbreaks of rain in the west. high pressure close to the near continent will keep the north and east largely dry, so we'll see some changes in the weather from place to place. western areas likely to see the heaviest of the rain, particularly towards wales and southwest england. the driest, brightest weather is likely to be across more eastern parts of the uk as we go through the week ahead. that's your latest weather. bye for now. live from washington, this is bbc news. the us airdrops thouands of meals to hungry gazans in a joint operation withjordan. aid experts say it's not enough amid a deepening humanitarian crisis. ukraine shakes up its military leadership as kyiv says children are among at least eight people killed in a russian drone attack in odesa. former us president donald trump and his republican presidential challenger nikki haley return to the campaign trail ahead of super tuesday. hello. i'm helena humphrey. it's good to have you join us. the us has carried out an airdrop of aid into gaza, using three military cargo planes. us central command said it dropped more than 38,0000 meals along the gaza coastline in a joint operation withjordan�*s airforce. the uk, france and egypt have already airdropped aid into gaza, but this is the first time the us has done so. negotiations over a temporary ceasefire are expected to restart sunday in cairo. us officials say israel has endorsed a framework of a proposed truce and hostage release, but hamas has yet to agree to it. meanwhile, israeli war cabinet member benny gantz will visit the white house monday to meet with us vice president kamala harris. they're expected to discuss a humanitarian truce as well as reducing palestinian civilian casualties and increasing deliveries of aid. international calls are intensifiying for accountability for recent violence, including
