Two Palestinian boys have been killed after Israeli tank shells hit a UN-run school in Gaza - hours before Israel's security cabinet is expected to vote on a proposal for a unilateral ceasefire.
The boys, aged five and seven, died and 25 other Gazans were wounded as they sought to shelter in the school run by the UN relief and works agency (Unrwa) in Beit Lahiya, northern Gaza.
The school is the third UN shelter to be hit by Israeli fire in its 22-day war on the territory.
The attack came as heavy artillery and aerial bombardment of what Israel described as "Hamas targets" continued on Saturday.
Christopher Gunness, an Unrwa spokesman, said several rounds hit the UN school at about 6:45am. The third floor of the school took a direct hit after a short pause, killing the pair and injuring another 14 people.
Witnesses said four more people were killed when other shells struck nearby as people tried to escape.
