The number of missing persons in the Palestinian enclave, reached more than 3,750 people, the office said.
"The death toll in Gaza has reached 12,000 people, including 5,000 children," the statement said.
On October 7, the Palestinian resistance movement Hamas launched a surprise large-scale rocket attack on Israel from the Gaza Strip, breaching the border and killing and taking captives in nearby Israeli military sites and communities. The movement said its operation, Al-Aqsa Flood, was in response to Israeli provocations and occupation of Palestinian territories.
Israel launched retaliatory strikes and ordered a complete blockade of the Gaza Strip, home to more than 2 million people, cutting off supplies of water, food and fuel. On October 27, Israel launched a large-scale ground incursion into Gaza, ostensibly to eliminate Hamas fighters and free Israeli captives.
