RIYADH – Six militants who attacked a Saudi border post with Yemen last week killing five security officers on both sides were all Saudi nationals, the Saudi Interior Ministry said on Tuesday. Five of the gunmen were killed in the confrontation with security forces, including two who blew themselves up, while a sixth was wounded and arrested. The ministry named the culprits, saying they were “all wanted Saudis” who were identified through DNA tests and that four of the gunmen had done time in jail, according to a statement carried by the Saudi Press Agency. The ministry had said that the militants attacked the Wadia border post in the south of the Kingdom on Friday. The ministry identified the militants as Moussa Abdullah Mohammed Al-Bakri Al-Shihri, who was released after serving his jail term for his involvement in terrorist crimes and activities; Ayyoub Saleh Abdulaziz Al-Suwaid, whose family had already reported his absence and that they had received a call from him about his presence in an area of conflict; Saleh Ali Saad Al-Omari, who was released after serving his jail term for his involvement in terrorist crimes and activities; Faraj Yaslam Mohammed Al-Sayari, who had served his prison term and was flogged for his involvement in the issues of drug abuse, and his family had reported his departure from the Kingdom to head to areas of conflict; Abdulaziz Ibrahim Abdullah Al-Rashudi, who was later released after he was arrested from areas of conflict. The Council of Ministers early Tuesday strongly denounced the vicious attack targeting the security men at the Wadia border post. The Cabinet considered this assault as treacherous attack carried out by a deviant group that does not respect the sanctity of the holy month of Ramadan. It also expressed deepest condolence to the families of martyred securitymen, asking Allah Almighty to bestow mercy on their souls and wishing a speedy recovery for the injured. On Monday a Saudi court jailed four Saudis for traveling to Iraq to fight. Meanwhile, three mortar bombs landed inside Saudi Arabia on Monday close to its northern border with Iraq. The mortars caused no casualties. Authorities said they were still looking into who fired Monday's rounds, which landed near a block of flats outside the northern town of Arar. Custodian of the Two Holy Mosques King Abdullah last week said he was stepping up security following. In February, King Abdullah decreed that traveling overseas to fight would incur long prison sentences. – Agencies
