DEIR AL-BALAH, Gaza Strip (AP) — Israeli fighter jets hit targets in the Gaza Strip minutes after a weeklong truce expired on Friday, signaling that the war with Hamas has resumed in full force. Black smoke billowed from the besieged territory and Israel dropped leaflets over parts of southern Gaza urging people to leave their homes, signaling it was preparing to widen its offensive. Renewed hostilities heightened concerns for the about 140 hostages who remain in Gaza, after than 100 were freed as part of the truce. It came a day after U.S. Secretary of State Antony Blinken met with Israeli officials and urged them to do more to protect Palestinian civilians as it seeks to destroy Hamas. Meanwhile, negotiators continued talks to restart the truce, according to mediator Qatar.
