The deal between Israel and Hamas to release hostages being held in Gaza and begin a ceasefire was officially signed by negotiators in Doha on Thursday, according to two sources familiar with the issue.

The deplorable humanitarian conditions in northern Gaza have caused bitter infighting within the Biden administration.

Israeli Prime Minister Benjamin Netanyahu has delayed a vote to approve the Gaza ceasefire deal, due on Thursday, accusing Hamas of seeking last-minute changes to the agreement. US Secretary of State Antony Blinken said a "loose end" was being tied up and that he was confident the ceasefire would still begin on Sunday as planned.
