Israel is coming under increasing pressure to agree to an extension of a four-day pause in its war with Hamas.

U.S. President Joe Biden said he supports prolonging the cease-fire, which is due to end on Tuesday morning and part of a deal to free hostages held by Hamas in Gaza. The halt in fighting is "critically needed” for additional aid to get into the territory and for more captives to be freed.

"This deal is delivering life-saving results,” Biden told reporters on Sunday. "This deal is structured so that it can be extended to keep building on these results. That’s my goal. That’s our goal: to keep this pause going beyond tomorrow.”
