Pakistan would be prepared to return the Indian pilot shot down and captured this week if it helped ease the crisis with its neighbour, Pakistan’s foreign minister has said.
"We are willing to return the captured Indian pilot if it leads to deescalation," Shah Mahmood Qureshi told Pakistani television station Geo TV.
He also said the Saudi foreign minister was expected to visit Pakistan with a special message from Crown Prince Mohammed Bin Salman, who visited both Pakistan and India earlier this month.
Indian and Pakistani troops traded fire briefly along the contested border in Kashmir this morning, a day after the two nuclear powers both downed enemy jets over the disputed region of Kashmir, with Pakistan capturing the Indian pilot, Wing Commander Abhinandan Varthaman.
The United States, China and other world powers have urged restraint from the two nations as tensions escalate following tit-for-tat airstrikes in the wake of a suicide car bombing that killed at least 40 Indian paramilitary police in Indian-controlled Kashmir on 14 February.
Events have sparked fears of India and Pakistan, who have fought two wars and countless deadly skirmishes over Kashmir, entering a cycle of retaliation and counterattacks that could spiral out of control.
Commander Varthaman, who rapidly attained hero status in his own country, has become the face of the escalating conflict, with analysts touting him as a potential trump card for Islamabad and perhaps the key to bringing the arch-rivals back from the brink.
"History tells us that wars are full of miscalculation. My question is that, given the weapons we have, can we afford miscalculation," Mr Khan said during a brief televised broadcast to the nation.

Troops from India and Pakistan briefly exchanged fire in Poonch, a district in Indian-occupied Kashmir, according to a statement from the Indian army.
India claims the incident was initiated by Pakistan and lasted for a little over an hour, but was significantly less elevated than the artillery fire exchanged by the two sides yesterday.
India is building more than 14,000 bunkers for families in Jammu and Kashmir state living close to the border, hoping to keep them safe near their homes rather than evacuate them.
Yesterday, India's foreign ministry handed a dossier to Pakistan that it claimed detailed camps of the Paskistan-based militant group that carried out the 14 February attack.
The latest escalation marks a sudden deterioration in relations between the two countries.
As recently as November, Mr Khan spoke of "mending ties" with India.
The White House urged "both sides to take immediate steps to de-escalate the situation."
