The ministry said 26-year-old Nayer Musallam Hammad Al-Nijeidi Al-Bluwi, a Saudi, carried out Monday's attack, adding that he had a history of drug abuse, read an Interior Ministry statement on the Saudi Press Agency. The security spokesman named the four martyred security men in the Madinah suicide bombing in the vicinity of the Prophet's Mosque as privates Muhammad Bin Mutad Hilal Al-Muwallad, Hani Bin Salim Saleem Al-Subhi, Abdulmajeed Bin Abdullah Owdah Al-Harbi and Abdulrahman Bin Naji Saleem Al-Jihani. May Allah have mercy on their souls and accept them as martyrs. The spokesman said that on July 4 (Ramadan 29) the security men suspected a man who was walking towards the Prophet's Mosque across an open area that is used as a car park for visitors. When they intercepted him, he blew himself up with an explosive vest he was wearing. This resulted in the martyrdom of the four security men. The investigations in the other terrorist incident that took place on the same day near one of the mosques neighboring Souq Mayyas in Qatif governorate yielded three names of the attackers. The perpetrators of the terrorist blast in Qatif were identified as Abdulrahman Saleh Muhammad Al-Imir (23), who was detained in 2013 for participating in riots calling for the release of detainees being held for their involvement in terror cases. The second terrorist was identified as Ibrahim Saleh Muhammad Al-Imir (20) and the third was identified as Abdulkareem Ibrahim Muhammad Al-Hasani, 20. All the three have not obtained Saudi national identity cards. The ministry said investigations have led to the arrest of 19 suspects, including 12 Pakistani nationals and 7 Saudis, involved in the attacks in Madinah, Qatif and Jeddah. The statement added that examination of the remains from the two terror attacks in Madinah and Qatif "revealed the presence of the explosive Nitroglycerin", which it said was similar to the substance found in the scene of the bombing at Soliman Fakeeh hospital parking lot in Jeddah. The spokesman added that the authorities were still conducting tests.
