Israeli strikes killed 77 Palestinians in Gaza in the past 24 hours, health authorities said on Sunday, as Egypt hosted an Israeli delegation for a new round of talks in a bid to secure a truce with Gaza's Hamas rulers.

The Israeli military said it killed a senior Islamic Jihad militant in a strike on a command centre in the courtyard of the Al-Aqsa Hospital in central Gaza. It did not mention his name or rank.

"The command centre and terrorists were struck precisely, the military said, adding it was intended to minimise "harm to uninvolved civilians in the area of the hospital".
