RAMALLAH, West Bank — Israeli settlers beat and killed a 20-year-old Palestinian American man during a confrontation in the Israeli-occupied West Bank, and a second Palestinian was fatally shot, according to Palestinian authorities and the families of both men.

The Israeli military did not confirm or deny the deaths, but said there had been a violent exchange Friday between Palestinians and Israeli civilians near the West Bank town of Sinjil, where the two deaths were reported. The Shin Bet, Israel’s domestic intelligence agency, and Israeli police were looking into the reported casualties, the military said.

The U.S. Embassy in Jerusalem confirmed the death of the man with U.S. citizenship, identifying him as Seifeddin Musalat, but did not address the circumstances. U.S. officials have asked Israel for further details, the embassy said.

Musalat, 20, was born in Florida and returned to the West Bank last month to visit family, his cousin, Diana Halum, said.
