Israeli settlers killed a 20-year-old Palestinian-American man in the West Bank, according to the Palestinian Ministry of Health and an eyewitness, as settler violence against Palestinians ramps up in the occupied territory.

A 20-year-old American was allegedly beaten to death by Israeli settlers while visiting family in the West Bank, according to Palestinian health officials and his family.
