Six Palestinians were killed in an Israeli military offensive on the West Bank city of Jenin on Friday, the Palestinian health ministry said. The ministry had previously put the death toll at five people.

The Israeli operation in Jenin was the latest in a series of clashes in the West Bank between Israeli forces and Palestinians. The violence had been escalating for more than two years but picked up in intensity since Hamas fighters based in the coastal enclave of Gaza led an attack on Israel last October.

Palestinian authorities say seven people were killed during an Israeli military attack and airstrike around the West Bank city of Jenin.
