Over 600 people were killed in an Israeli airstrike on Baptist Hospital in Gaza on Tuesday, Health Ministry spokesman Ashraf al-Qudra told Anadolu.
Pictures emerging from Al Ahli Arab hospital show scenes of chaos - with bloodied and maimed casualties being rushed out on stretchers in the darkness.
Hundreds of displaced people had been sheltering in a hall on the hospital grounds, according to locals.
Civil defence officials say the explosion was the result of an Israeli airstrike and that hundreds are trapped in the rubble.
The airstrike comes on day 11 in the current conflict, with a growing international chorus of non-governmental groups and world leaders saying the Israeli bombing campaign on the besieged Gaza Strip-including healthcare facilities, homes, and houses of worship-violates international law and may constitute a war crime.
