Israeli strikes across Gaza killed 42 people on Wednesday as the military intensified a siege on northern parts of the Palestinian territory, forcing the World Health Organization to pause the latest phase of its polio vaccination campaign, medics and officials said.

Israeli forces began the operation in the north about three weeks ago with the declared aim of preventing Hamas fighters from regrouping. The operation has intensified since the killing of Hamas chief Yahya Sinwar a week ago, despite hopes from the US that his death could provide a fresh impetus for peace.
