Militants firing from Afghanistan on Tuesday shot dead seven Pakistani paramilitary soldiers, officials reported.
"Heavy fire from across Pak Afghan border early morning today on a Frontier Constabulary check post northeast of Angoor Adda in South Waziristan," Pakistani military said in a statement.
The attacks coming from Afghanistan is likely to raise the tension between the two countries, since they both say more should be done by the other side to prevent crossborder attacks.
Both countries accuse each other for not doing enough to stop Taliban fighters and other militants.
The killings of the members of the paramilitary Frontier Constabulary (FC) occurred near a border town in the mountainous South Waziristan region.
Militant groups such as the Taliban and Al Qaeda have presence in the region where the fire was opened.
Taliban attacks in Afghanistan have increased since early July, when both the Taliban and the Afghan government confirmed that the Taliban’s leader Mullah Omar died two years ago.
The Afghan government held first direct peace talks with the Taliban delegates in July. However, the Taliban group rejected the negotiations following the death of the group’s top leader Mullah Omar.
Afghanistan accuses Pakistan of not taking part in peace talks with Taliban.
Pakistan, on the other hand, claims Pakistani Taliban has bases in Afghanistan and its leadership operates from there.
Pakistani Taliban and Afghan Taliban are two different organisations with loose ties.
Afghan President Ashraf Ghani since coming to office tried to improve ties with Pakistan however after a series of attacks in Kabul directly accused Pakistan for not doing enough against the group.
"Pakistan still remains a venue and ground for gatherings from which mercenaries send us messages of war," Ghani said
"We hoped for peace, but war is declared against us from Pakistani territory; this in fact puts into a display a clear hostility against a neighboring country."
