Pakistan says two of its soldiers have been killed after the Afghan Taliban launched an operation against military positions along their shared border late on Thursday, BBC reported. 

Three others were injured as Pakistani forces responded to the "unprovoked fire", Information Minister Attaullah Tarar said.

Both sides claim to have inflicted heavy losses in the clashes. People in Pakistan's border regions told the BBC they had heard explosions and were asked to move to safety, according to BBC.
