More than 100 Palestinians were killed and dozens wounded in an Israeli strike on a Gaza school sheltering displaced people, the Hamas-run Gaza government said on Saturday, an airstrike the Israeli military said had targeted a Hamas command center.

The strikes hit when people sheltering at the school were performing dawn prayers, leading to many casualties, the Hamas media office said in a statement. Medics had not yet been able to reach all the bodies, it said.

There was no immediate information from Gaza health authorities.
