again. it's day two of the trial of derek chauvin. he's the former police officer charged with the murder of george floyd in may last year. on day one, both sides laid out their cases, and today the prosecution is continuing to make its case. as part of that, we've been hearing from witnesses. first was donald williams iii — he has a background in mixed martial arts and he can be heard on footage of the arrest yelling at the police to get off george floyd. here's the prosecution questioning him. at some point, did she make it 911 call? . , . ., . at some point, did she make it 911 call? . , . call? that is correct, i did call the police- — call? that is correct, i did call the police. why _ call? that is correct, i did call the police. why did _ call? that is correct, i did call the police. why did you -

call the police? i called the olice. he was then cross examined by the lead defence lawyer eric nelson. he questioned mr williams about his martial arts background and about the timing of his arrival at the scene. and in this combative exchange, mr nelson questioned mr williams about his own conduct during the arrest. and it is fair to say that prior to your arrival there, and it is fair to say that prior to yourarrivalthere, knew and it is fair to say that prior to your arrival there, knew had no idea what had been going on in the area? like i say, ijust saw that. i didn't— like i say, ijust saw that. i didn't know what was going on. he didn't know what was going on. testified didn't know what was going on. he: testified that as you came around the corner, the energy sort of appeal due to budget incident. that is totally correct. so, you would have absolutely no idea that an ambulance was called three minutes before you arrive. i ambulance was called three minutes before you arrive.— before you arrive. i don't know an hinu before you arrive. i don't know anything about _ before you arrive. i don't know anything about that. _ before you arrive. i don't know anything about that. you -

several significant developments to bring you on the coup in myanmar. first, around 2000 refugees have been turned back by thailand. this is the thai prime minister. translation: some villagers arrived and we asked — translation: some villagers arrived and we asked about _ translation: some villagers arrived and we asked about problems, - translation: some villagers arrived and we asked about problems, and i and we asked about problems, and they said there weren't any. we then said, can you go back first? we didn't point any guns in their faces. we shook their hands and even wish them well. that is humanitarian. up until now, most of the resistance to the coup has come from the civil disobedience movement. now, though, armed ethnic groups are becoming involved too — one of the biggest is the karen national union. and over the weekend the burmese military carried out air strikes against the group here in territory that it controls in karen state. as you can see, the state sits on myanmar�*s border with thailand. this was the aftermath of the air strikes. and these were the first aerial attacks in the area for 20 years. this footage was sent to us by aid group free burma rangers working inside myanmar. this is its spokesperson. many of the air were conducted at night, which is a capability they didn't have before. we have not seen in that districts, so this is a new capability. it was a hit at night and diwali, in northern karen state, on the whole valley is hiding now. altogether, we have 10,000 people in this place. then the planes came, and went along the border, forming karen, placesjust on and went along the border, forming karen, places just on the burma side of the border. this karen, places 'ust on the burma side of the border.— of the border. this is what happened next. ethnic karen families went into hiding — some of them even took shelter in caves. 0thers took boats across the salween river to thailand. reports suggest that injured people were allowed in — but that most people were pushed back. we're also told that those who couldn't cross the river were sent to a displacement camp on the myanmar side of the border. then there's this footage. it appears to show thai border guards putting up barriers to keep people away. a local thai official has told reuters the army was sending most burmese back as it deemed the situation over the border to be safe. that isn't an assessment shared by the people fleeing. this is the account of one karen woman who fled. the bramleys army is living all advantages. we don't want this any more. the soldiers are close by and give us trouble all the time. the number of armed men we are seeing tells you this is a very tense border with myanmar, and the karen people who have been coming, many of them injured, four years have known something that young activists in the cities of myanmar are now learning at first hand. that they myanmar military, far from defending people, wages war against them with a pitiless savagery, crossing them as enemies. but many of those people _ crossing them as enemies. but many of those people were _ crossing them as enemies. but many of those people were turned - crossing them as enemies. but many of those people were turned back- crossing them as enemies. but many of those people were turned back by| of those people were turned back by thailand. , , ., , , thailand. they were stopped in the 'untle b thailand. they were stopped in the jungle by security _ thailand. they were stopped in the jungle by security personnel- thailand. they were stopped in the jungle by security personnel is, - jungle by security personnel is, trying to prevent them from coming further into thailand. so just kind of like pushback from there. this is kind of like a deterrence not to have too many of them coming in. and then once this has been lifted, the government has to say, no, we're not trying to push them back, we welcome them, but we have our professional ways of dealing with people. burmese refugees are also trying to enter india — and that's led to a crackdown there too. we're told the border state of manipur had originally told officials to 'politely turn away�* new arrivals. it's since reversed that order. with more on this, here's the bbc�*s anbarasan ethirajan in delhi. what the authorities did was, they were watching what was happening in the neighbouring north indian state, for hundreds of people from myanmar have already taken refuge, and the government of india is concerned about what it means for its relations with the myanmar government at the moment, the militaryjunta there. in the last few days, there are reports that many myanmar nationals are trying to flee the violence, and one doctor was quoted as saying by the reuters news agency that people had been admitted to a hospital in manipur with gunshot wounds. because the border is not clearly demarcated, there are lots of forested areas, it is very easy within this border in manipur, once you move away from the border crossing it is like you don't know where you are, so it is easy for these people to cross into manipur. many armed groups in myanmar spent decades fighting the military for greater control — and now some are helping the anti—coup movement. here's david eubank again from free burma rangers. there is a new feeling from the burma people saying we had no idea, so sorry, we just focus on allowance, the suffering he had under the government, please help us. on the ethnic people are saying we will have all that we can barely stop the army ourselves, they have done two things — they have sent money for food and medicine, done two things — they have sent money forfood and medicine, and some of the targeted leaders of the protesters, the ethnic some self have smuggled out to safety. but the ethnic army, since they don't have the power to stop the burma army, but they are trying to work together. right now, there is no large international support that gives them the power they need to make a difference. each group is fighting for their lives. of course, there are concerns myanmar could descend into a multi—faceted conflict. in the past few hours, the karen ethnic group warned that burmese ground troops were advancing on its territory and has called for international help to stop what it called an 'onslaught�*. and the broader context here is that armed ethnic groups in myanmar control about a third of the country. soe win than, bbc burmese service in london. first of all help us understand the extent to which these ethnic groups and their armed wings are able to control parts of myanmar. since the independence _ control parts of myanmar. since the independence in _ control parts of myanmar. since the independence in 1945, _ control parts of myanmar. since the independence in 1945, myanmar - control parts of myanmar. since the | independence in 1945, myanmar has experienced this kind of civil war. a little bit of history, myanmar is made up of major different ethnic groups, there are over 100 ethnic groups, there are over 100 ethnic groups in myanmar. karen, wejust talked about, is one of the biggest groups. they all have their own army, they are looking for more autonomy from the central government. they have been waging this war against the central government for over seven decades, but in recent years, the government had made ceasefire agreement with a different ethnic groups. there are still groups which have not signed any ceasefire agreement with the central government. karen national union is one of them. they have signed it. but they overrun a military outpost and says that military outpost and says that military outpost and killed a few of the soldiers and captured some of them, so military attacks, we talked about this area per garment, under the marching towards those and karen are pushing these refugees towards the thai burma border. bud are pushing these refugees towards the thai burma border.— the thai burma border. and so how eas is the thai burma border. and so how easy is this — the thai burma border. and so how easy is this alliance _ the thai burma border. and so how easy is this alliance between - the thai burma border. and so how easy is this alliance between the i easy is this alliance between the protesters in the city against the coups and these ethnic armed groups, because these groups after or are looking for more autonomy from the central government, and some of these protesters in the city want to give power back to the democratically elected central government.— democratically elected central government. ., , ., ., , government. yeah, but for now they have a common _ government. yeah, but for now they have a common enemy, _ government. yeah, but for now they have a common enemy, so -
