Reports from Pakistan say security forces have arrested two men suspected of links to the al-Qaida terror network.

The reports say the two were arrested Tuesday in the southwestern city of Quetta. They say one of the men has been identified as an Iraqi national, while the nationality of the second suspect is unclear.

Pakistan is a key ally in the U.S.-led war against terrorism. Its security forces have arrested hundreds of al-Qaida suspects.

Pakistan's semi-autonomous tribal region of South Waziristan near the Afghan border is considered a possible hideout for al-Qaida leader Osama bin Laden. Pakistan's army believes some 600 to 700 militants are still in the region despite repeated efforts to flush them out.
