More than 300,000 people have signed online petitions calling for Pakistan prime minister Imran Khan to receive a Nobel peace prize after he freed an Indian pilot in a bid to defuse tensions with his country's arch-rival neighbour.
The capture of wing commander Abhinandan Varthaman had become the focus of renewed hostilities between the nuclear-armed rivals which have alarmed the international community.
Tensions have soared since a suicide bombing in Kashmir last month claimed by Pakistan-based militants killed 40 Indian paramilitaries.
The hashtag #NobelPeaceForImranKhan began trending on Twitter on Thursday after Khan unexpectedly announced that the captured pilot would be released as a "peace gesture".
Abhinandan -- whose MiG fighter was shot down a day earlier as he chased Pakistani jets over disputed Kashmir -- was returned to India late Friday.
Two similarly-worded campaigns on the change.org platform launched by users in the UK and Pakistan called for Imran Khan to be nominated for next year's prize "for his peace efforts and dialogues in the Asian region on diverse conflicts".
They have gained more than 240,000 and 60,000 digital signatures respectively.
Pakistan's information minister Fawad Chaudhry Saturday also submitted a resolution in the country's parliament demanding Khan be given the award for his contribution to peace in the region.
"Imran Khan played a sagacious role in de-escalating tension between Pakistan and India," the resolution said.
In his speech announcing Abhinandan's release, Khan referred to the catastrophic consequences of nuclear war as he called for talks with New Delhi.
Thousands of people around the world are allowed to make nominations for the Peace Prize, including members of parliament and government ministers, former laureates and some university professors.
