Indian military officials have welcomed Pakistan's planned return of a captured pilot, but refused to confirm they would de-escalate a conflict between the two nuclear powers.

The pilot, identified as Wing Commander Abhinandan, became the human face of the flare-up over the contested region of Kashmir following the release of videos showing him being captured and later held in custody.

"We are happy our pilot is being released," said Air Vice Marshal RGK Kapoor, at a joint news conference of India's three armed forces on Thursday evening.
