Israel cuts off Gaza in 'total siege'
Israeli Defense Minister Yoav Gallant announced Monday that he has ordered a "total siege" of the neighboring Gaza Strip, allowing no food, fuel or electricity to enter the Hamas-ruled territory.
"We are fighting barbaric terrorists and we will act accordingly," Gallant said.
Since Saturday's surprise attack on Israel launched by Hamas militants, Israeli forces have struck back. Hundreds of buildings and homes have been destroyed in Gaza, leaving more than 123,000 people displaced, according to the United Nations.
Unlike Israel, the Gaza Strip has no air raid sirens or bomb shelters. Over 73,000 people are currently sheltering in schools, according to the U.N.
Meanwhile, hospitals in Gaza are struggling to cope with the number of casualties, the U.N. said. At least 493 people have died and another 2,751 have been injured there, according to the Palestinian Ministry of Health.
