Israel is blockading Gaza and refuses to allow in fuel, saying it could be used by the Hamas militant group for their military goals. The U.S. was "working on a mechanism that can get fuel to where it's needed" in Gaza, he said. Medical authorities in Hamas-run Gaza said on Tuesday that 8,525 people including 3,542 minors had been killed. Distribution is particularly hard in northern Gaza, the main focus of Israel's military operation, aid officials say, and some have halted all deliveries. World Health Organization (WHO) spokesperson Christian Lindmeier said on Tuesday it had sent no further aid to northern Gaza hospitals since Oct. 24, citing a lack of security guarantees.
