The Iranian Foreign Ministry on Tuesday condemned a series of terrorist bomb attacks in the Saudi Arabian cities of Medina, Qatif, and Jeddah.

“Terrorism knows no borders or nationalities and has no solution but the creation of international and regional consensus and solidarity against it,” said Iranian Foreign Ministry Spokesman Bahram Qasemi.

Reiterating that Iran condemns all manners of terrorism, he noted that all countries must unite against the sources and reasons behind terrorisms.     

Iranian Foreign Minister Mohammad Javad Zarif also tweeted, “There are no red lines left which the terrorists have not passed.”

Earlier in the day, four security guards were killed when a terrorist detonated his explosives near the security headquarters of the Prophet's Mosque in Saudi Arabia's western city of Medina.

"Security forces suspected a man who was heading towards al-Masjid al-Nabawi (the Prophet's Mosque) as he passed through a visitors parking lot," said a statement released by the Saudi interior ministry. "As they tried to stop him, he blew himself up with an explosive belt causing his death, and the death of four security personnel.”
