JERUSALEM (JTA) — Masked Palestinians attacked police at the Temple Mount with stones and firebombs for the second morning in a row.

Israeli security forces arrived at the scene of the incident at the Mughrabi Gate on Tuesday morning and pushed the protesters back into the Al-Aksa Mosque at the site. Twelve protesters were arrested and several police officers were injured.

The incident occurred on the morning of the fast day of Tisha B’Av, as thousands of Jewish worshippers gathered below the Temple Mount at the Western Wall for special prayers for the day of mourning, which marks the destruction of both the First and Second Temples in Jerusalem.

The Temple Mount was open to visitors after the incident. Extra security measures were put in place in the old city for the fast day, according to police.
