Israel is still holding a Palestinian-American teenager it arrested July 3 during protests in Jerusalem, following the murder of Mohammed Abu Khdeir.

"I can confirm that Mohamed Abu Nie is a U.S. Citizen … was arrested on July 3rd during protests in the Shuafat neighborhood in East Jerusalem," Marie Harf, a U.S. State Department official, said during a briefing earlier this month.

"The embassy’s also in frequent contact of Mohamed’s family and his lawyer. We are calling for a speedy resolution to this case," she said.

Harf said a consular official attended the boy's hearing on July 22 and visited him on July 31. She said the United States was "gravely concerned over the prolonged detention of this U.S. citizen child." However, the department has not made any official statements about the boy since August 7.

Another Palestinian-Israeli teen, Tariq Abu Khdeir, a cousin of the murdered boy from Tampa, Florida, was also arrested on July 3. However, his arrest, in which he was brutally beaten, was caught on camera, and his status as a relative of Mohammed Abu Khdeir, kept his name in the public eye, and he was released and allowed to return to the United States in mid-July.

The United States embassy in Tel Aviv had not yet responded to an Haaretz inquiry into the matter at the time this report was published.
