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 launch barrels 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. Our 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. And 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. 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 overnight. 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 munition 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, 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. Joining me live is angela stent, director of the centre for eurasian, russian and east european studies at georgetown university. Always great to have you on the programme. We heard their ukraine hitting those two russian weapons depots. Doesn't seem to you that ukraine is increasingly targeting more and russian assets on the other side of the border there? well, it certainly _ side of the border there? well, it certainly is _ side of the border there? well, it certainly is trying _ side of the border there? well, it certainly is trying to, side of the border there? well, it certainly is trying to, and it certainly is trying to, and it certainly is trying to, and it has succeeded to some extent. It's drone capacity has really grown. Its ability to fight electronic warfare has grown. It is targeting more and more in russia, but as your correspondent said, president volodymyr zelensky is arriving in the us, and tomorrow he is already going to meet with officials, and he is seeking permission for ukraine to use american and other european weapons to strike further into russia's heartland. russia's heartland. Well, do ou russia's heartland. Well, do you think. russia's heartland. Well, do you think, then, _ russia's heartland. Well, do you think, then, in russia's heartland. Well, do you think, then, in those you think, then, in those conversations we are expecting him to have, this kind of success might factor in he might be able to convince us officials to go ahead and maybe loosen the reins of it? i officials to go ahead and maybe loosen the reins of it? loosen the reins of it? i think the peeple loosen the reins of it? i think the peeple in _ loosen the reins of it? i think the people in the _ loosen the reins of it? i think the people in the biden the people in the biden administration still are very concerned about the dangers of escalation and about a possible how the russians would retaliate to us weapons being used to strike further into russia's heartland. There's a big debate about that here, and there are many people who say there are many people who say the us has too concerned about escalation. So i think what president zelensky is also hoping is that president biden has his legacy to think about. He has between now and december, or20 he has between now and december, or 20 january, he has between now and december, or20 january, let's say, when the next president is inaugurated, to consider that legacy and you maybe take some bolder steps. And i think the ukrainians are hoping that particularly in the time between the election on fifth of november and the inauguration on 20 january that they might be able to secure permission for this. They might be able to secure permission for this. What about russia, permission for this. What about russia. Do _ permission for this. What about russia. Do you _ permission for this. What about russia, do you think? permission for this. What about russia, do you think? does permission for this. What about russia, do you think? does it i russia, do you think? does it have an answer right now for these ukrainian counterattacks, of course for the incursion by ukraine that we saw? how do you expect russia to respond? well, the russians. _ russia to respond? well, the russians, again, _ russia to respond? well, the russians, again, as russia to respond? well, the russians, again, as your russians, again, as your correspondent said, they are pushing back certainly in the east. They are taking more territory. They are also pushing back in the course region, which of course the ukrainians have occupied for a few weeks now, and so i think one russian answer is to try to push the ukrainians out of the kursk region. But we may see more russian escalation, again, more russian escalation, again, more weapons and ammunition arriving from north korea. Jones and other weapons are arriving from iran, so russia is not short on these kinds of weapons. Is not short on these kinds of weapons_ is not short on these kinds of weaons. ~. ,, ~. weapons.

The like north korea? well, first of all, the russian _ like north korea? well, first of all, the russian military l of all, the russian military has been building up his own suuply, has been building up his own supply, certainly, in the last year they recovered from the initial problems they had when they first invaded ukraine and they first invaded ukraine and they were unsuccessful in achieving their goals. But i was at a conference in kyiv last week and it was clear that this increase, particularly in the supply of north korean ammunition, is a great concern to the ukrainians. to the ukrainians.

This is a very brutal war which is continuing. It shows no signs of abating. He is going to meet both with president biden and with vice president harris, and he said that he would like to meet, and has requested a meeting, with former president trump. So he really would like to come back and show his own people that the us is reconsidering the restrictions that it's put so far on the use of these weapons. that it's put so far on the use of these weapons.

We have seen the impact, really, this kind of technological warfare in the conflict between hezbollah and israel.

Iwouldn't reasons why the ukrainians have banned it. I wouldn't use the word paranoia for that. Interesting stuff. Angela stent, with georgetown university, we always appreciate your time. Thank you.
