The Saudi kingdom has seen a rise in the number of attacks lately.
An attack on a security checkpoint in the Al-Salam Palace in Jeddah left two royal guards dead and three others wounded. The attacker was reportedly killed in the incident.
Authorities have also been carrying preventive assaults on terrorist hideouts in a move to foil attacks.
