At least five soldiers and 15 militants were killed in three separate attacks involving a gunfight and two bombings in northwestern Pakistan, officials said Tuesday.

At least five soldiers and 15 militants were killed in three separate attacks involving a gunfight and two bombings in northwestern Pakistan, officials said Tuesday.

The gunfight erupted overnight at a check post of the paramilitary Frontier Corps (FC) in Shireendara area of Orakzai district, one of Pakistan's seven semi-autonomous tribal regions on the Afghan border.

"More than 50 militants attacked the check post. Two soldiers embraced shahadat (martyrdom) while 15 terrorists were killed in an exchange of fire," a senior security official told AFP.

He said six soldiers also sustained injures in the attack, adding that the militants fled after the FC troops retaliated.

Another security official confirmed the incident and casualties.
Elsewhere, one soldier was killed and another wounded when a roadside bomb went off near their vehicle in the northwestern town of Bannu on Tuesday, a security official said.

Separately, a bomb planted on a roadside in restive Bajaur tribal district's Chargoo village bordering Afghanistan killed two tribal security force personnel and wounded three others, local government official Sohail Khan told AFP.

The officials were overseeing the security arrangements for a door-to-door anti-polio vaccine in the region where Taliban militants are active, he added.
Pakistan is home to 85 percent of polio cases around the world in 2014.
