Pakistani intelligence officials say two roadside bombs have killed two soldiers and wounded two others in a restive northwestern region.

Two intelligence officials said three soldiers sweeping the road ahead of a military convoy on the road between the towns of Miran Shah and Razmak in North Waziristan were hit Sunday by a bomb planted near an intersection. Two died and one was wounded. They spoke anonymously because they weren't authorized to speak to media.

The same officials reported a second blast on the Mir Ali-Miran Shah road near a checkpoint, but that wounded only one soldier.

The Pakistani army recently carried out several offensives in tribal regions along the Afghan border but is reluctant to conduct a massive sweep of the militant stronghold of North Waziristan, despite US insistence.
