Confirmed it had fired missiles over the border early sunday. Hezbollah said on telegram it had targeted israel's ramat david airbase, 20 kilometres south of the city of haifa. Air raid sirens were also triggered in several areas of northern isarel, including near haifa, according to israel. These pictures show part of an intercepted rocket launched from lebanon that fell in nazareth in israel in the early hours of sunday. It comes in the hours after the israeli military carried out what it called extensive strikes on hezbollah targets in southern lebanon. Israeli aircraft destroyed thousands of hezbollah rocket launchers in southern lebanon, according to israeli officials. Also tonight, the us state department is urging american citizens to leave lebanon, with fears growing of an allout war. Meanwhile, the death toll from israel's strike on a densely populated area of southern beirut on friday has risen to 37. Hezbollah says 16 of its members were killed in the attack, including senior military commander ibrahim aqil. He was wanted by the us government for years and was designated a global terrorist for his involvement in the 1983 bombing of the us embassy in beirut. Friday's bombing also killed civilians, including three children, with more feared trapped in the rubble. Middle east correspondent orla guerin reports from the scene in beirut. A beirut suburb turned into a battlefield. They are standing on the ruins of a sevenstorey building in the hezbollah stronghold of dahieh. Israel says this was a precision strike. It doesn't look very precise. Well, the search for bodies is continuing here now. Rescue workers are still picking through the rubble. The strike took place in the middle of this densely populated residential area. The result for hezbollah has been the loss of a top military leader and other senior commanders. It is another blow to an organisation that is looking exposed and weakened. But the dead here also included women and children, and every member of the daqduqi family. Still counted among the missing fouryearold naya ghazi. Local people gathered today waiting for news, fearing what it might be. Some said the attack would change nothing. People absorb the shock and they start their life again. It's hard, but this is the way we choose, and we will not stop. We have to defend our country. We have to defend our border. We have to defend our people from any aggression, from israelis orfrom others. Hezbollah has been burying some of those killed by israel yesterday. They were carried aloft on anger and defiance. The iranianbacked group is fighting on, firing volleys of rockets across the border today. And israel has been hitting hard, with dozens of fighter planes bombing southern lebanon, targeting hezbollah rocket launchers, israel says. If the international community was concerned before, it will be far more worried tonight. Orla guerin, bbc news, beirut. In gaza, palestinian health officials say at least 22 people were killed in an israeli strike on a school. Officials said most of the victims were women and children who were sheltering there. Israel's military says it was targeting a hamas command room. There are reports that an unborn child was among those killed. Bbc verify has looked at several videos of the aftermath. Clips appear to show a foetus being carried by a civil defence worker. To the occupied west bank, where israeli forces have raided aljazeera's office in ramallah that's according to the news organization. You're looking now at pictures from aljazeera's broadcast, when it says heavilyarmed israeli troops handed a 45day closure order to a staff member. The soldiers say an israeli court issued the closure. Israel banned journalists from the qataribased network from operating inside the country back in may, when it shut down aljazeera's offices in eastjerusalem. Israel says the network was a threat to the country's security. At least 12 people have been injured in a russian bomb attack on an apartment building in ukraine's secondlargest city, kharkiv. The assault on saturday came hours after ukrainian drone attacks on two russian ammunition depots one in the southwestern region of krasnodar, the other in toropets a town in russia's northwestern tver region. Ukrainian officials say more than 100 drones were used in the operation, which also focused on targets in russianoccupied crimea. Russia says it shot down 18 ukrainian drones our europe correspondent, jess parker, reports. A fireball erupting into the night sky as ukraine staged a major drone attack. This, says kyiv, was a russian ammunition depot that included supplies it believes are from north korea one of two munitions stores ukraine claims to have hit last night. Translation: these were. Warehouses of russian tactical missiles and guided aerial bombs, all that russia uses for terror against our cities, our positions. Ukraine has been ramping up these kinds of attacks, demonstrating a growing drone strike capability. But what kyiv really wants is permission to use westernmade longrange missiles on targets deep inside russia permission president zelensky has confirmed he still doesn't have. He is heading to the us this coming week seeking further support, and this military analyst says the recent drone attacks are all part of kyiv*s wider political message. The point is that ukraine could show to our western partners and the biden administration that even without western permission, western missiles, we could achieve our targets and our goals in russian territory. But of course, with western missiles, it could be better, more massive, more concentrated and more effective. In russia, authorities released footage of what it says are evacuees following last night's drone strike, while in ukraine, moscow's bombs continue to cause devastation. Its troops try to push further into ukraine. One constant is the growing toll of victims. Jessica parker, bbc news, in kyiv. William taylor is a former us ambassador to ukraine. He's just returned from kyiv. I talked about all this with him a little earlier. You were actually in ukraine, in kyiv, last week. What was the atmosphere there like? carl, the atmosphere there is reflecting the offensive, the attack into russia, that the ukrainian military are undertaking. It's good for morale. That's kind of a change, isn't it? it hasn't always been that way. I've been there eight times since the big war started, and it varies. Morale varies depending on how things are going on the battlefield, and they are going better now. Still, people are worried. You know, they're holding territory inside russia and they're trying to defend down in donetsk, but it is a highrisk operation. Now, let's talk about these strikes within russia 2,000 tons of weaponry destroyed by these ukrainian drones, according to ukraine. How effective do you think these ukrainian drone strikes have been for the country? very effective. I saw an estimate that three months' worth of shells, artillery shells, were destroyed in that one thing. That means that three months' worth of artillery shells killing ukrainian soldiers have been destroyed, have been blown up. And some of these glide bombs, these really big and accurate glide bombs that were going into the trenches where ukrainian soldiers are, were also destroyed. A lot that came from north korea, a lot that has come from russia. Do you think that some of that success that you mention there, using their own weapons would that be an impetus to press and maybe convince us allies that they should be able to use western weapons to do exactly the same thing? i don't see why not i don't see why not. If the russians are firing at them, the ukrainians ought to be able to fire back. They've been able to do that when we've given them the authority to use our weapons in the short term, barely across border. This is going deep, as you say, and those are military targets big ammo dumps. That's having an effect on the russians' ability to pursue this war. It will be a busy week coming up for ukrainian president volodymyr zelensky, isn't it? he's coming over here to the united states. He is expecting to be meeting with president, the vice president, donald trump. He'll be at the un meetings. What do you expect from zelensky coming? we got some indication last week in kyiv. He was very clear he didn't want to give details of his proposal. He's got a victory plan, and he is going to present this victory plan, as you said, first to president biden. He made it very clear he's not going to disclose what's in it. He made a commitment to president biden that he would talk to him him first, but then he will tell the rest of his country. It's going to have a military component, an economic components, a diplomatic component, and this would be a way to push the russians toward negotiations to end this war. Is this, do you think, too little, too late? does ukraine actually have a path, do you think, typically, plan or no plan? i think they do, carl. I think they do. A lot depends on us. If we could provide them with the weapons they need, and as you indicate, the authority to use those weapons deep into russia at military targets, taking away those ammo dumps, then yes, the ukrainians can push the russians very hard and push the russians back, so that the russians will figure out putin will figure out he can't win. He can't outlast them. Again, that's if we continue to provide what we've been providing so far. So speaking to many us leaders, and also will be at that united nations meeting, presumably meeting with several other of his allies there. Do you think this is going to be a crucial week for zelensky? it'll be an important week, there's no doubt. He puts a lot of stock in this victory plan. He has said many times, both to us last week and in preparation for this trip, that a lot depends on the united states. And when he comes and talks to the people that you mentioned, he is hoping to get some kind of a commitment that will allow him to move forward. Let's look at russia now before i let you go. There was a recent report by our bbc colleagues that found that more than 70,000 russian troops have now died in this conflict. Where do you think russia's military stands? does it have the capacity still to fend off these sorts of drone attacks, and also, of course, dealing with an incursion as well? it is, it's dealing with an incursion, and ukraine still occupies a good chunk of russia. And there were 100 drones that attacked that ammo dump. 100 drones going 300 kilometres or more over a lot, and they weren't shut down. So it is the right question: do the russians have the ability to continue to fight? interesting stuff, as always. Bill taylor, the former us ambassador to ukraine from 2006 to 2010, always good have you here. Thank you, carl. The us, australia, india, and japan announced a new maritime security agreement and a joint coast guard mission on saturday, as the summit of the socalled quad alliance wrapped up in delaware. The alliance's joint statement also expressed the quad is seriously concerned about the situation in the south china sea. It's us president biden*s final quad summit of his presidency and he's aiming to cement the importance of the alliance to countering china's rise in the indopacific. Daniel russel is vice president for international security and diplomacy at the asia society policy institute, and former assistant secretary of state for east asian and pacific affairs. Hejoined me a little earlier. What did you make of what we're hearing now coming from that summit statement that concern about the situation in the south china sea? there's very close alignment among the four on their concerns about the behaviour of china. Interestingly, the statement doesn't mention china per se, but it does focus on the challenges and the problems. And one of the biggest ones and it's important that india is fully on board with that statement is the assertive behaviour and the ruleflouting behaviour that china is manifesting against small countries and neighbours in the south china sea. Is there anything of course, besides some kind of strong language in this document coming out of the summit that these four countries think they might be able to do to counter china's presence there? well, one of the important initiatives from the quad is something called the indopacific maritime domain awareness initiative. And that's a very long name for what really is the four countries putting their national satellite technology and also their private satellite information at the disposal of these small island nations, these small coastal nations, so that they can track the massive fishing fleets as well as the paramilitary coastguard activities of china and protect and defend not only their exclusive economic zones but importantly the resources in them the fish stocks and the minerals and so on. So it's not a headon confrontation, but this satellite surveillance information is otherwise unavailable to the countries. Moreover, what the four leaders today have agreed is to significantly bolster coastguard exercises and coastguard training for the countries in southeast asia and beyond, so they're looking at both the pacific ocean and the indian ocean. So these things do matter. It was also an interesting setting for this summit, wasn't it, taking place in the actual home of the president there in delaware. Well, it was at his home for the bilateral meetings and at his old high school for the meeting of the quad leaders. 0h, interesting, 0k. You've got to chuckle that this is sort of the ultimate revenge for somebody who wasn't necessarily first in his class at high school, and i think bidenjoked a little bit about that. But it wasn't a nostalgia summit. They weren't singing auld lang syne. They were getting real work done, important work, and they generated real outcomes. I mentioned the maritime security initiatives, but in technology, importantly in public health, in other areas, they produced programmes that directly benefit communities in southeast asia, in south asia an
