Israeli settlers killed a 23-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 Palestinian American man was beaten to death by settlers in the Israeli-occupied West Bank, says the Palestinian Health Ministry, prompting his family to demand that the U.S. lead an investigation.

The two men, including a dual US citizen, were killed when Israeli settlers attacked the town of Sinjil, according to the Palestinian health ministry.
