MIRANSHAH, Pakistan, June 9 (Reuters) - A suspected Talibansuicide bomber rammed a truck into a Pakistan militarycheckpoint on the border with Afghanistan on Monday, killingfour soldiers, military officials said.
One military source said seven soldiers were wounded.
The assault, which took place in Pakistan's North Waziristantribal region, came just hours after Taliban militants disguisedas security forces stormed Pakistan's busiest airport in thecity of Karachi.
"The death toll could increase," a military official toldReuters.
No group immediately claimed responsibility for the attackbut the officials said the Pakistan Taliban were responsible.
Last week, a suspected suicide bomber attacked a Pakistanisecurity forces vehicle in Rawalpindi, home to Pakistan's armyheadquarters, killing five people including two officers.
Sunday night's attack on an airport in Karachi and anincreasing number of assaults on military outposts in the lastfew weeks have all but destroyed prospects for peace talksbetween the Pakistani Taliban and the government.
In May, Pakistani forces launched their first majoroffensive in years against Taliban militants near the Afghanborder after several rounds of government-led talks aimed atending an insurgency failed.
Disagreements over how to handle the insurgency have marredrelations between Prime Minister Nawaz Sharif and the army,which has been pushing for a major military offensive. (Writing By Mehreen Zahra-Malik; Editing by Nick Macfie)
