A roadside bomb attack on Sunday killed Pakistan's two senior military officers and a soldier in the country's troubled northwest, along with six others, the military said.

Major General Sanaullah and Lieutenant Colonel Touseef were visiting troop posts in the Upper Dir district of northwestern Khyber Pakhtunkhwa province, along the Afghan border, when their vehicle hit a planted bomb killing them along with a soldier.

"Maj Gen Sanaullah and Lt Col Touseef embraced Shahadat (martyrdom) this morning. They were returning after visiting troops posts on Pak Afghan Border," the military said in a statement, adding that the incident resulted from an IED planted on the road near the border.

The statement added that the roadside bomb near the border also killed a sepoy, or private soldier, and injured two other soldiers.

Separately, two roadside bomb attacks in Miranshah, the main town in North Waziristan tribal district bordering Afghanistan, killed two soldiers on Sunday and wounded four others, security officials said.

In the neighboring district of Bannu Taliban militants ambushed a convoy of tribal police early Sunday, killing two of them and wounding four others, the officials said.

Pakistan says more than 40,000 people have been killed as a result of bomb and suicide attacks carried out by Taliban and Al-Qaeda-led militants who oppose Islamabad's US alliance.

Though no group has yet claimed responsibility for the attack, it took place at a time when the Pakistani government are trying to begin peace talks with the Taliban, aimed at ending more than a decade of bloodshed.
