The sprawling mosque where the Prophet Muhammad is buried is visited by millions of Muslims from around the world each year during pilgrimages to Mecca. The area would have been packed with pilgrims for prayer during the final days of the Muslim holy month of Ramadan, which ends this week.
The Interior Ministry could not be immediately reached for comment.
This is the third such attack in the day after a suspected suicide bomber blowed himself up near the US consulate in Saudi Arabia’s Jeddah city.
Two security officers were injured "as a result of the failed bombing", Al Jazeera reported.
Local media reports said the attacker parked his car outside a mosque opposite the consulate and shortly afterwards detonated his device after being tackled by security guards.
The Jeddah consulate was the scene of a militant attack in 2004, which left nine people dead.
