The detention of an Indian border guard by Pakistani forces has injected another element of tension into the already volatile confrontation between the two countries after last week’s deadly terrorist attack in Kashmir.

He was detained on Wednesday, a day after the terrorist attack in the Indian part of Kashmir, which killed 26 civilians and has pushed the nuclear-armed neighbors to the verge of military confrontation.

India has accused Pakistan of having a hand in the attack and has indicated it is preparing a military strike, in addition to other punishing measures it has already laid out. Pakistan has denied the accusations and reciprocated with its own retaliatory measures.
