U.S. and Arab mediators have made some progress in their efforts to reach a ceasefire accord between Israel and Hamas in Gaza, but not enough to seal a deal, Palestinian sources close to the talks said on Thursday. As talks continued in Qatar, the Israeli military carried out strikes across the enclave, killing at least 17 people, Palestinian medics said. Qatar, the U.S. and Egypt are making a major push to reach a deal to halt fighting in the 15-month conflict and free remaining hostages held by Islamist group Hamas before President Joe Biden leaves office.
