At least 20 Palestinians have been killed in the occupied West Bank Israel’s largest military operation in the occupied territory in decades.

Israeli forces are conducting raids in Jenin, in the occupied West Bank, blocking access to aid for Palestinians in the besieged refugee camp on the fourth day of its assault.

Dozens of Israeli soldiers were stationed on the outskirts of the Jenin refugee camp, with Israeli military jeeps and armored personnel carriers moving into the area.
