A suicide bomb attack has been reported in Saudi Arabia’s city of Medina, close to the Prophet’s Mosque, one of Islam’s holiest sites.
The Prophet’s Mosque is the burial place of the Prophet Muhammad and Medina the second-holiest city in Islam after Mecca.
There has also been another explosion near a mosque in the eastern Saudi Arabian city of Qatif.
A witness said one explosion had destroyed a car parked near the mosque in Qatif as the suicide bomber blew himself up outside a Shia mosque without causing any other injuries.
This was followed by the second explosion just before 7 p.m. local time.
Qatif is known to be home to many of the kingdom’s Shi’ite Muslim minority.
The incident happened just hours after a suicide bomber was killed and two people were wounded in a blast near the U.S. consulate in the kingdom’s second city of Jeddah on Monday.
It was the first bombing in years to attempt to target foreigners in the kingdom.
There was no immediate claim of responsibility for the Jeddah attack.
Islamic State has carried out a series of bombing and shooting attacks in Saudi Arabia since mid-2014 that have killed scores of people, mostly members of the Shi’ite Muslim minority and security services.
