What we knowNegotiations in Cairo are at an impasse as Israeli Prime Minister Benjamin Netanyahu called Hamas' demands "delusional," in a statement yesterday and said there was no point in further negotiations without a change in their position. Hamas is seeking a permanent cease-fire and the release of 1500 prisoners in exchange for hostages. Netanyahu also said yesterday that the military remains intent on continuing its offensive into Rafah, on the border with Egypt, where about 1.4 million Palestinians are seeking refuge.Israel's plans are in defiance of the international community and the United States. President Joe Biden, Vice President Kamala Harris and Secretary of State Antony Blinken, have publicly stated that the U.S. cannot support a ground invasion into Rafah without a credible and implementable plan for ensuring the safety of the people sheltering there.The International Court of Justice will begin historic hearings tomorrow about the legality of Israel's 57-year occupation of the West Bank, Gaza and east Jerusalem. The siege of Nasser Hospital by Israeli forces in Khan Younis enters its fourth day. More than 100 people have been detained, including staff members. About 10,000 people are sheltering at the hospital complex, which is struggling under heavy fire and dwindling supplies. Heavy construction on the Egyptian side of the border with Gaza are stoking Palestinians' fears of expulsion. Israel denies plans to do so, and the Egyptian president rejected the displacement of Palestinians, but its foreign minister said: “it is not our intention to provide any safe areas or facilities, but … we will provide the support to the innocent civilians, if that was to take place.”
