President Joe Biden and President-elect Donald Trump are both claiming credit for Israel and Hamas agreeing to a ceasefire deal in Gaza after the White House brought Trump's Middle East envoy into negotiations that have dragged on for months.

Donald Trump said on Wednesday he would use the Gaza ceasefire deal as momentum to expand the Abraham Accords, U.S.-backed agreements struck during the president-elect's first term that normalized Israel's relations with several Arab countries.
