TEL AVIV: Hundreds of Palestinians are feared dead after a huge blast at a hospital in Gaza City, blamed by the Hamas group on an Israeli air strike, BBC reported.

Israel says the blast was caused by rockets misfired by another group, Palestinian Islamic Jihad, and both sides deny blame, the report said.

US President Joe Biden is visiting Israel today but a planned summit in Jordan with Arab leaders has been cancelled, according to the report.

At least 600,000 Palestinians have fled the northern Gaza Strip for the south since Israeli military warnings.

Israel has blocked essential supplies to Gaza in retaliation for a Hamas attack on 7 October that left 1,300 Israelis dead.
