At least 18 Palestinians have been killed and 30 more wounded in the occupied West Bank, where Israel has launched its largest military operation in two decades. Israeli forces have simultaneously raided four cities and refugee camps in the north, with hundreds of soldiers backed by armored vehicles, bulldozers, fighter jets and drones.

Much of the violence has been centered on Jenin, a frequent target of raids by Israeli forces, but this latest military operation is the largest since the Second Intifada. Ahmed Tobasi, artistic director at the Freedom Theatre in Jenin refugee camp, says Israel’s tactics are about “punishing the people, punishing the civilians,” with an ultimate goal of ethnic cleansing. “They want Palestine empty from Palestinians.”

He also calls on the U.S. public to speak out against continued military support for Israel, saying the killings in both Gaza and the West Bank are only possible because Israel has “the green light from the U.S. government.”
