Saudi Arabian security officials have identified the terrorists who carried out the recent attacks in Madinah and Qatif areas resulting in the martyrdom of four security men.

Following an intensive investigation, 19 persons - seven Saudis and twelve Pakistanis - who were involved in the terrorist attacks in Madinah, Qatif and Jeddah, have been arrested, the officials added.  
One of the bombers, who carried out the Madinah blast, was identified as Naer Musllam Hammad Al-Nijaidi Al-Balawe, a 26-year-old Saudi citizen with a history of drug abuse.

Al-Balawe crossed a parking lot next to the mosque in Medina and detonated an explosive belt near a security headquarters, killing four soldiers, the state news agency SPA quoted an Interior Ministry spokesman as saying.

"When security guards intercepted him he blew himself up," said the spokesman.

According to an Interior Ministry spokesman, the following persons have committed Qatif terror attack: Abdulrahman Saleh Mohammed Al-Amer, 23-years-old, formerly detained two years ago for having been involved in a mob calling for the release of terror-related detainees; Ibrahim Saleh Mohammed Al-Amer, 20-years-old; and Abdulkareem Ibrahim Mohammed Al-Hasini, 20-years-old. All of them are Saudis who have not obtained the national identity cards.

Examinations of the remains of the two terror attacks in Madinah and Qatif revealed the presence of the explosive Nitroglycerin substance, similar to the substance found in the bombing that took place at Sulaiman Faqih hospital parking lot in Jeddah, the spokesman said, adding that the concerned authority is still conducting the pertinent tests.

He concluded that a pursuant statement would be issued on the new developments of the ongoing investigations into those crimes.-Reuters
