Gaza’s civil defence agency said on Sunday an Israeli strike on a mosque-turned-shelter in central Deir al-Balah killed 21 people, while Israel’s military said it had targeted Hamas militants.

“The number of deaths rose to 21 and a large number of wounded as a result of the occupation (Israel) bombing of a mosque sheltering displaced people in front of the gate of Al-Aqsa Martyrs Hospital in Deir al-Balah in the central Gaza,” said agency spokesman Mahmud Bassal.
