Pakistani military officials say a roadside bomb has killed two soldiers and wounded another in a restive tribal region bordering Afghanistan.

Officials told reporters Sunday the blast occurred Saturday while the soldiers were on routine patrol in the North Waziristan region near the Afghan border. There has been no claim of responsibility..

Pakistani forces have been battling Islamic militants in the area for some time. Tension has been building for months in North Waziristan since the Pakistani army completed a series of offensives against al-Qaida militants and their supporters in neighboring South Waziristan.

In July, Pakistani, U.S. and Afghan forces reported killing more than 60 suspected foreign militants and Taleban insurgents in a series of clashes in the region.
