According to israel. 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. Israel is believed to have been behind the attack. It has not denied responsibility but has not taken credit either. 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 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. With me is william taylor, former us ambassador to ukraine.
