Al-Kiswani was detained several times before by Israeli police for the intelligence service.
Al-Aqsa Mosque is the world's third-holiest site for Muslims. Jews call the area the "Temple Mount," claiming it was the site of two Jewish temples in ancient times.
Since 2003, Israel has allowed settlers into the flashpoint compound almost on a daily basis with the exception of Fridays and Saturdays.
Israel occupied East Jerusalem, where Al-Aqsa is located, during the 1967 Arab-Israeli War. It annexed the entire city in 1980 in a move never recognized by the international community.
