Palestinian medics say that more than 280 people have been killed and more than 600 injured as Israel's bombing of the impoverished Gaza Strip continued for a second day.
A police station and a factory were among the sites reportedly hit on Sunday, after a mosque and the headquarters of al-Aqsa television had been struck overnight.
Reports said air attacks on Sunday afternoon struck east of Gaza City, in Khan Yunis, and Jabaliya, in the north.
Witnesses also reported seeing more than 10 explosions along the border with Egypt close to sunset, in what was said to be an attack on underground tunnels used to smuggle goods into Gaza.
Many people were said to be reported wounded in the strike.
