Israeli strikes flatten buildings, mosques in Gaza

Death toll rises to 313 in Gaza, with close to 2,000 wounded, as tensions continue to escalate on the second day.

At least 313 Palestinians have been killed as Israel struck 426 targets in Gaza, its military said, flattening residential buildings in giant explosions.

Among those killed in Gaza were 20 children. About 2,000 others are wounded, the Palestinian Ministry of Health said.

The United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) said more than 20,000 Palestinians left Gaza’s border region to head further inside the territory and take refuge in UN schools.

Nebal Farsakh, the spokesperson of the NGO Palestinian Red Crescent Society (PRC), told Al Jazeera that their medical teams were facing “great challenges” in Gaza, adding that they had called on the international humanitarian community to open humanitarian corridors so that NGOs like them could safely carry out their work of helping people in the Gaza Strip.

On Saturday night, Energy Minister Israel Katz said Israel would halt the electricity supply to the besieged territory. The Palestinian enclave – home to some two million people – has been under an Israeli air, land and sea blockade.
