The liberal Israel lobby J Street also called for a US-led investigation into the death. The family of a 20-year-old Palestinian-American man they say was beaten to death Friday by Israeli settlers in the West Bank has called on the U.S. State Department to investigate the incident.

U.S. citizen Sayafollah Musallet, 20, also known as Saif, was killed in the incident on Friday evening in Sinjil, north of Ramallah.

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.
