Hello. You're live with BBC News. I'm Anna Foster here in Southern Israel, where authorities seem to have blocked humanitarian aid from entering the Gaza Strip after that weeklong troop collapsed yesterday. The fighting restarted yesterday morning as both sides blamed each other for the collapse of the agreement. But one consequence of that appears to be the lack now of any humanitarian aid at all entering the Gaza Strip through the Rafeh crossing. Well, this is the scene just now looking across at Northern Georgia. We know that there have been many airstrikes overnight. A spokesman for the Israeli military said that they were now hitting Hamas targets all over the Gaza Strip. And we've seen ourselves this morning from this position here, again, those heavy pools of smoke rising over Gaza as that fighting resumes. And we've heard as well, the regular sound of outgoing fire from here. We know that Israeli airstrikes have also hit areas in northwestern Gaza and also in Khan-Yunis in the south. That is one of the places where hundreds of thousands of people fled earlier in the war to escape the fighting when it was focused on the north. Well, the Hamas Run Health Ministry said that 200 people were killed and more than 600 have been injured since the fighting restarted in Gaza at seven o'clock yesterday morning.

Reports also say that Khan units, which we were speaking about there in the south of the Strip, is now seeing some of the heaviest bombardments since the war began. The Israeli military has also been dropping leaflets in parts of Gaza, warning people to leave or to move away from the focus, the new focus of this renewed fighting. And as that's been going on, we've also seen a renewed bombardment of rocket attacks towards Israel, Hamas, and some of the armed groups in Gaza have been firing rockets towards Israel. And we've seen, including here in Stirot, the Iron Dome defense system be deployed to actually intercept them in the sky. Each side is accusing the other of breaching the cease-fire deal. And yesterday evening, as we were talking about those intensive talks that were still going on in Doha to try and bring things back on track, it appears, and certainly sources have told the BBC that for now, at least, that appears unlikely. Well, let's start with this report from our Middle East correspondent, Hugo Beisheiger.

The respite lasted one precious week. War returned to Gaza yesterday. A ceasefire expired and Israeli fighter jets resumed their bombing. Two-hundred strikes in one day, Israel says. Ran Unis in southern Gaza was heavily hit. Hospitals already overcrowded struggle to cope. Israel says it is targeting Hamas, but children are again among the victims.. Lana says she was with her mother and younger brother when the attack happened. Her older brother was still missing. A UN official was inside a Gaza hospital when the choose came to an end.

This hospital simply cannot take more children with the wounds of war. There are children everywhere. These children are sleeping. There was a bomb literally 50 meters from here.

Here, a QR code which links to a map of the Gaza Strip, broken down into hundreds of blocks, places for people to go. The humanitarian crisis continues and may get worse. The UN says no aid entered Gaza from Egypt yesterday, and there's no guarantee any deliveries will happen today. In Southern Israel, the military says it shot down 50 rockets fired from Gaza. Israel and Hamas traded blame for the end of the truths. Talks for a new deal seem to have collapsed, and the Israeli bombing continues. Many of our nation's still hope for peace and are again, count to the dead.

Well, as that firing continues from here in Southern Israel towards Gaza, our Geyser correspondent, Rooshdi Abu al-Louf, who is currently in Istanbul, gave me this update a little earlier on the renewed Israeli military operation in Gaza and how people there were feeling right now.

The focus of the operation seems to be now in the south, not in the north. Well, the north was bom also last night and this morning heavily, but the main focus now is the four main areas, four main villages: east of Canyones, Abassan, Banis Hilla, Khozaa, and Abassan, the biggest it's called in Arabic, Abassan Kabira. It's been bombed heavily. Hundreds of targets, tens of targets in the area were destroyed, including government buildings, houses, agricultural area. It's the area that about 40% of the gaza, vegetables and fruit are grown up in this part of the gaza. Most of the people who live there are farmers. We have seen images and pictures of people walking their cows, walking their camels and their donkeys, early morning and leaving this area. The people they live there, they have a very bad experience about the Israeli ground in Kyrgyz back in 2014. When Israel re-equipped out about three kilometers along this area, hundreds of people were killed and hundreds of buildings were destroyed back in 2014. The people of this area, they knew very well how the consequences of a possible Israeli ground troops being sent to this area. They decided to leave to the west.

The west is already by over a million Palestinians who were forced to leave their homes back in the October the 13th from Kansas City and the north, where the focus of the Israeli operation before this seven days truth was in the north and people were displaced to the south and so the area was people lived in two of each other. I have been living with those people for four weeks in the area and I know that there is no more room for any people to come to the suffering. The humanitarian cost of this war is getting bigger and bigger and the people are unable to cope with the situation, especially after the weather change from summer to winter and people left homeless without proper clothes and without proper shelter to cope with this weather condition. Now in addition to all of that, they have to receive another thousands of people who are fleeing their homes in the Eastern part and east.

That's Rishdie, Abu Al-Fa, our Gaza correspondent who's in Istanbul at the moment. We were talking about the fact that no humanitarian aid went from Egypt into Gaza at all yesterday. The suggestion is that might be repeated again today. That takes us really right back to the situation at the beginning of the war, when the Rafeh crossing was closed, even before the ceasefire that we've seen, when we see a situation where no aid at all is passing into the Gaza Strip. I spoke a little earlier to Juliette Tuma from UNRA on that topic. That's the UN Agency for Palestinian refugees, and she warned of dire humanitarian consequences for civilians there.

We do know that there are exerted efforts to renew the delivery of humanitarian assistance, and we also call for not only going back to the pose, which brought quite some respite to people in Gaza, but also for humanitarian ceasefire. The scenes that you were just showing, what your colleague was just talking about multiple displacement. The hospital, Nasr Hospital, which by the way, I visited when I was there just last week, one of the very few medical facilities that are still available in Gaza. We are at the doorstep of a humanitarian man-made tsunami in the Gaza Strip.
