Saudi Arabia on Tuesday suspended prayers inside all its mosques except the holiest two sites in Islam as it steps up efforts to contain the new coronavirus, state media reported.
Mosques will be temporarily shut for the five daily Islamic prayers as well as the weekly Friday prayers, the official Saudi Press Agency said, citing the council of senior scholars -- the kingdom's highest religious body.
It said mosques would continue to issue the ritual call to prayer.
The decision seeks to direct worshippers to pray at home but does not affect prayers in Mecca's Grand Mosque and the Prophet's Mosque in Medina, it added.
The announcement risks riling fringe hardliners, for whom religion trumps health considerations.
