U.S. Ambassador to Israel Mike Huckabee said on Tuesday he had asked Israel to "aggressively investigate" the killing of a Palestinian American who was beaten to death by Israeli settlers in the occupied West Bank,

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.

Sayfollah Kamel Musallet, who lived in Tampa and was an American citizen, his family said, was visiting relatives in the West Bank when he was killed.
