Two Militants Blow Themselves Up In Southern Saudi Arabia

DUBAI (Reuters) - Two suspected Al Qaeda militants blew themselves up Saturday after being trapped inside a government building in southern Saudi Arabia, the Interior Ministry said, following an attack on a border post with Yemen that also killed four security men.

An Interior Ministry spokesman said the pair were part of a group of six Al Qaeda militants who attacked the Wadia border post Friday from Yemen. Three of the militants were killed Friday and a fourth was captured after being injured.

Saudi Arabia, the world's biggest oil exporter, has long viewed its 1,800 km (1,100 mile) border with impoverished, conflict-ridden Yemen as a major security problem and has been building a fence to deter militants and criminals.

Interior Ministry spokesman Mansour al-Turki said security forces surrounded the two men in the second floor of the local intelligence service building in al-Sharurah area after they had forced their way into the building Friday. They were invited to surrender.

"At an early hour this morning ... the two attackers resorted to blowing themselves up," Turki said in remarks carried by state news SPA.

Saudi-owned Al-Arabiya television earlier reported the militants had put up "stiff resistance" to security forces surrounding them, firing automatic weapons and hurling grenades at security forces, but there were no reports of casualties.

Saudi Arabia had been wary of potential Al Qaeda infiltration from Iraq where militants have swept through the country's Sunni Muslim heartland near the border with Saudi Arabia.

In the south, Al Qaeda in the Arabian Peninsula has been waging a campaign of attacks on Yemeni government targets raising fears the violence could spill across the border to Saudi Arabia.

The kingdom overcame its own Al Qaeda insurgency almost a decade ago, but said in May it had detained 62 suspected Al Qaeda militants with links to radicals in Syria and Yemen whom it said it believed were plotting attacks on government and foreign targets in the kingdom.

SIX MILITANTS

Turki said Friday's attack began when six militants in a car with licence plates from an unspecified Gulf Arab country arrived at the Wadia checkpoint in the Empty Quarter desert area, which links Yemen's Hadramout province with Saudi Arabia.

The militants shot and killed the commander of a Saudi border patrol and seized his car. They made their way inside Saudi territory towards Al-Sharurah.

Security forces engaged the militants in the second car, killing three and capturing the fourth. The militants also killed two other security men during the clash, Turki said.

Saudi media had earlier said the six were all Saudi nationals. Turki said authorities were conducting tests to determine the identities of the militants.

Yemen's state news agency Saba earlier reported a suicide bomber drove a car laden with explosives into the Yemeni side of the Wadia border crossing, killing himself and one soldier and wounding another.

After the attack, Yemeni security forces chased militants who fled from the scene in two cars into the desert, Saba said, citing a military source. But a Yemeni official, apparently referring to the same incident, earlier told Reuters the gunmen had escaped into Saudi Arabia after attacking the Yemeni border post. The official said the attackers were Al Qaeda militants. The Wadia crossing links Saudi Arabia withYemen's southeastern Hadramout province, which stretches through arid valleys and empty desert -- a landscape Al Qaeda militants use to their advantage across the Middle East. Saudi Arabia's construction of the security fence along its border with Yemen has often been interrupted by protesting tribesmen who say it prevents them accessing pastures for their livestock.
