Israeli Prime Minister Benjamin Netanyahu is considering a plan to force all Palestinian civilians out of northern Gaza, including Gaza City, in order to lay siege to Hamas and force the release of hostages.

Palestinian authorities say 15 people were killed overnight in the Gaza Strip in multiple Israeli attacks. An airstrike early Friday morning in Gaza City hit a family home, killing six people including an unknown number of children, Gaza’s Civil Defense said. Another person was killed in Gaza City when a strike hit a group of people on a street.

Khaled Meshal, one of Hamas’s most senior officials, said in an interview that the militant group expects to play a decisive role in the enclave when the war is over.
