Israel's Home Front Command eased some war-related restrictions from midday Thursday, allowing limited activity and permitting public gatherings of up to 50 people as long as they were near shelters.

The military said workplaces were allowed to reopen as long as they were near shelters, but schools and other educational institutions would remain closed.

"In order to safeguard public safety and human life, all holy sites in the Old City -- including the Western Wall, Al-Aqsa Mosque, Temple Mount Complex and the Church of the Holy Sepulchre -- will remain closed, and entry will not be permitted to worshippers or visitors of any faith," a police statement said.

The Old City is located in east Jerusalem, which Israel occupied in 1967 and later annexed in a move that is not internationally recognised.

The ongoing closure coincides with the Muslim holy month of Ramadan, when tens of thousands of Palestinian Muslims would normally pray every Friday at Al-Aqsa Mosque.

Since the start of the war, the Israeli authorities have for security reasons barred access to the Old City for anyone other than residents or shopowners.

Israel, in coordination with the United States, began striking Iran on Saturday, killing supreme leader Ayatollah Ali Khamenei and sparking a regional war.

Retaliatory Iranian missile strikes have so far killed 10 people in Israel.
