Rep. Betty McCollum has asked the State Department to investigate whether the U.S. should cut off military aid to Israeli border police in response to the killing of two Palestinian teenagers last year.

The St. Paul Democrat wrote in a letter to the State Department that the shooting deaths of 17-year-old Nadeem Nawara and 16-year-old Mohammad Daher on May 15, 2014, demonstrate that “Israel’s treatment of Palestinian youth in the Occupied West Bank is unacceptable and must not be tolerated by the U.S. or the international community.”

The Times of Israel reported the two youths were killed after clashes between Palestinian protesters and Israeli soldiers during an annual commemoration of the displacement of Palestinians following the creation of the State of Israel.

McCollum, who released her letter to the public this week, said videos captured by security cameras showed the two teenagers were shot while “innocently walking down the street.” An analysis of the video showed “these children posed no threat to Israeli forces at the time they were killed,” she wrote.

The congresswoman asked the State Department to determine whether the killings violate the “Leahy Law,” which bars U.S. aid to foreign security forces that have “committed a gross violation of human rights.”

News media in Israel and elsewhere in the Middle East have covered McCollum’s letter.
