Aid group says one of its staff was killed when tanks pushed back into areas around al-Amal and Nasser hospitals

Israeli forces have besieged two more hospitals in Gaza, pinning down medical teams under heavy gunfire, according to the Palestinian Red Crescent.

All of our teams are in extreme danger at the moment and are completely immobilised," the humanitarian organisation told Reuters on Sunday, adding one of its staff was killed when Israeli tanks pushed back suddenly into areas around al-Amal and Nasser hospitals in the southern city of Khan Younis.
