Many Gazans have been attending funerals, following an Israeli offensive on Saturday in which more than 60 people died.
The death toll made it the territory's bloodiest day in years. Many of the casualties were civilians.
Gunmen are continuing to battle Israeli ground forces in Jabaliya refugee camp, one scene of Saturday's clashes.
Israel has been trying to seek out militants responsible for rocket attacks on its southern border.
But rocket attacks continue. Israeli police say 15 have fallen on the town of Sderot so far on Sunday.
Around 10 people were injured in the town, which is being targeted by around 50 rockets a day.
The Gaza bloodshed sparked anger in the West Bank, where stone-throwing youths attacked Israeli troops.
The troops responded with tear gas and rubber bullets. Witnesses said they shot dead a teenage boy.
