Storyline: Nearly 48,000 Palestinians have fled southward in the last two days from the Israeli military's ground offensive in Gaza City, UN humanitarians said on Tuesday. The UN Office for the Coordination of Humanitarian Affairs (OCHA) said that between mid-August and Monday, its partners observed more than 190,000 such movements, with many people traveling on foot due to the extremely high cost of transport. The partners reported that displaced families, often led by women and older people, were walking up to nine hours in extreme heat, frequently barefoot and with injured children, OCHA said. OCHA said its partners, providing support to those on the move, reported that more than 1,500 people, including more than 900 children, received urgent assistance, including psychosocial aid, water and medical care. Israeli forces dropped leaflets, urging people in Gaza City to move toward overcrowded "humanitarian zones" in central and southern Gaza. They said that Gaza City has become "a dangerous combat zone" and that they are determined to defeat Hamas there. "The situation is very difficult for us, and we have no money at all. My father is in poor health and needs help to push the handcart. There is no safe place in Gaza, and we'll have to sleep on the street like others tonight," said Alaa Ismail, a resident fleeing Gaza City, the Gaza Strip's largest urban center. "There is no safe place anywhere in Gaza. We don't know where our fate will lead to, and I can't be ensured that the place I'm heading to is really safe. As long as Israel wants it, their so-called 'safe zones' will become targets of attacks. As we stand here, news has just come in that tall buildings are facing strikes. Who can guarantee that Israel won't attack us?" said another displaced Gazan named Khalil Matar. While promoting southern Gaza as a safe zone for fleeing Palestinians, Israel has been implementing air strikes and bombardments on the areas, causing heavy casualties. The Gaza media office said in a statement on Tuesday that around 800,000 Gazans had gathered in southern Gaza Strip's Al-Mawasi area, where more than 2,000 people had been killed in more than 109 attacks by Israel, who designated the area as a "humanitarian zone."
