ISLAMABAD, Aug. 6 (Xinhua) -- A Pakistani soldier was killed in firing from across the Afghan border, Pakistan's army said Wednesday night.
An army statement said that mortar and heavy weapons were fired from across the Afghan border in Bin Shahi area of Dir district in Khyber Pakhtunkhwa province.
One soldier was killed while two got injured, the statement from the army's media wing, the Inter-Services Public Relations said.
The Pakistani Taliban claimed responsibility for the attack in a tweet.
Pakistani security officials have long been saying that militants have crossed border into Afghanistan as a result of major operations in the country's tribal regions.
The Pakistani militants routinely attack the border posts from the Afghan side.
Pakistan and Afghanistan have a nearly 2,600-km border, mostly porous. Pakistan is fencing the border with Afghanistan to block the movement of the militants.
Last week, Pakistan's army said that a soldier was killed when terrorists carried out a firing raid from the Afghan side of the border on a security forces' post in Bajaur district, a tribal district in Khyber Pakhtunkhwa.
