MUZAFFARABAD: A flare up between arch-foes India and Pakistan appeared to be easing on Saturday, a day after Islamabad handed back a captured Indian pilot, but tensions continued to simmer amid efforts by global powers to prevent a war between the nuclear-armed neighbours.Wing Commander Abhinandan Varthaman, who became the face and symbol of the biggest clash between India and Pakistan in many years, walked across the border just before 9 pm on Friday in a high-profile handover shown live on television. Shelling on both sides of the Line of Control (LoC) in the disputed Kashmir region continued after his release, resulting in four deaths, but then stopped overnight, officials said.Pakistan’s military on Saturday said its air force and navy ‘continue to be alert and vigilant’. Pakistan touted Abhinandan’s return as ‘a goodwill gesture aimed at de-escalating rising tensions with India’ after weeks of unease that threatened to spiral into war after both countries used jets for bombing missions this week.Global powers, including China and the United States, have urged restraint to prevent another conflict between the neighbours who have fought three wars since independence from Britain in 1947. Tensions escalated rapidly following a suicide car bombing on Feb 14 that killed at least 40 Indian paramilitary police in Indian-held Kashmir. India accused Pakistan of harbouring the Jaish-e Mohammad group behind the attack, which Islamabad denied.Indian warplanes on Tuesday carried out airstrikes inside Pakistan on what New Delhi called militant camps. Islamabad denied any such camps existed, as did local villagers in the area, but Pakistan on Wednesday retaliated with its own aerial mission, that led to Pakistan shooting down two Indian jets.The stand off came at a critical time for Modi, who faces a general election that must be held by May and who had been expected to benefit from nationalist pride unleashed by the standoff.Pakistani leaders say the ball is now in India’s court to de-escalate the tensions, though Pakistani army chief on Friday told top military leaders of the United States, Britain and Australia that his country would ‘surely respond’ to any aggression in self-defence.The Indian pilot’s ordeal since being shot down on Wednesday had made him the focal point of the crisis and he returned to his homeland to a hero’s welcome, with crowds thronging the Wagah border crossing and waving Indian flags.Before his release, Pakistani television stations broadcast video of Abhinandan in which he thanked Pakistan Army for saving him from an angry crowd who chased him after seeing him parachute to safety. “The Pakistani army is a very professional service,” he said. “I have spent time with the Pakistan army. I am very impressed.”On Friday, four Indian troops and one civilian were killed in a clash with fighters in the Indian-held Kashmir, where a further three people were killed and one wounded from Pakistani shelling.Pakistan’s military said two people were killed and two wounded since Friday afternoon in Azad Kashmir from a barrage of Indian shelling.Pakistani officials in Kashmir said the shelling stopped in the early hours of Saturday, but in a sign of the unease, residents say they are afraid another conflagration is likely. “The way situation is developing along the LoC makes me feel that both sides may collide head-on anytime now,” said Chaudhry Jahangir, a resident of the Samahni sector in Kashmir.
