Israeli police on Sunday detained two members of a prominent family in the contested Sheikh Jarrah neighborhood of Jerusalem who led protests against attempts by Israeli settlers to evict dozens of Palestinian families from their homes in the area.
The twin brother and sister were released later in the day.
The arrests of Muna and Muhammad al-Kurd, 23, came a day after police detained a well-known Al Jazeera reporter covering a demonstration in the neighborhood.
The reporter, Givara Budeiri, was held for four hours before she was released and sent to a hospital to treat a broken hand. It was not clear how her hand was broken, but her boss blamed police mistreatment.
