The Saudi Crown Prince Mohammed bin Nayef bin Abdul-Aziz has visited two security officers and a citizen who were wounded in coordinated bombings in the country.
The attacks on Monday killed at least four security officers and injured five others near one of Islam’s holiest sites in the Saudi city of Medina.
The crown prince who is also the country’s interior minister assured citizens that security is tight ahead of the end of the holy month of Ramadhan.
The attacks have rattled Saudis who are preparing to celebrate Eid al-Fitr from Wednesday.
No group has claimed responsibility but the Islamic State has carried out similar bombings in the past year
The suicide bombers targeted the holy city of Medina, the U.S. consulate in Jeddah and a Shi’ite mosque in the city of Qatif.
Medina is home to the second-holiest site in Islam. The city houses a mosque built by the Prophet Mohammed and his tomb.
