Air Canada has temporarily suspended flights to India amid growing tensions between that country and Pakistan.The airline had to turn back a flight en route to Delhi over the Atlantic Ocean and return to Toronto, Air Canada spokesperson Peter Fitzpatrick told the Star in an email Wednesday.Air Canada has suspended flights to India following a conflict between India and Pakistan, which led the latter to shut down its airspace. (Marcus Oleniuk / Toronto Star file photo)Data from the website flightaware.com indicated that the Air Canada flight, which departed Pearson airport Tuesday night, was over Scandinavia before turning back. The website shows that the flight was in the air for almost 14 hours and 20 minutes before arriving back at Pearson.A nonstop flight usually takes 13 hours and 45 minutes.A second flight from Vancouver to Delhi was also cancelled, Fitzpatrick said.The airline runs daily service to Delhi from both Vancouver and Toronto, while also running flights four times a week from Toronto to Mumbai.Air Canada is offering a “goodwill policy” for affected passengers.“We are monitoring the situation in order to resume service once the situation normalizes and we determine it is safe to do so,” Fitzpatrick said.On its website, Ottawa urges travellers to India to “exercise a high degree of caution.”Exercise a high degree of caution in India due to a continuing threat of terrorist attacks throughout the country at all times, the website said.Pakistan’s Civil Aviation Authority said it shut Pakistani airspace to all commercial flights Wednesday, without elaborating or indicating when the flights might resume. It was not clear if the shutdown applied to commercial overflights, though aviation authorities in Bahrain and the United Arab Emirates stopped all flights to Pakistan.Read more:Pakistan says 2 Indian warplanes downed, 1 pilot capturedIndia airstrikes in Pakistan hike tensions between nuclear neighboursPakistan said Wednesday it had shot down two Indian warplanes and captured two pilots in the disputed region of Kashmir, raising tensions between the two nuclear powers to a level unseen this century.The aircraft went down Wednesday morning in Kashmir, a mountainous region claimed by both India and Pakistan since almost immediately after their creation in 1947. One of the downed planes crashed in Pakistan’s part of Kashmir while the other went down in Indian-controlled section of the Himalayan region, Pakistan’s army spokesman Maj. Gen. Asif Ghafoor said.Pakistani troops on the ground captured an Indian pilot, he later said, after earlier saying it captured two. He did not explain what caused the confusion.An image from flightaware.com shows the Air Canada flight AC042, which departed Toronto on Tuesday night, en route to Delhi before turning back over Scandinavia. (flightaware.com)The pilot was injured and was being treated at a military hospital, Ghafoor said. He did not elaborate beyond saying the pilots were being “treated well” and made no mention of them being returned to India.“We have no intention of escalation, but are fully prepared to do so if forced into that paradigm,” he added.India acknowledged one of its air force planes was “lost” in skirmishes with Pakistan and that its pilot was “missing in action” on a chaotic day, which also saw mortar shells fired by Indian troops from across the frontier dividing the two sectors of Kashmir kill six civilians and wound several others. A helicopter crash in the region also killed six Indian air force officials and a civilian on the ground.Pakistan responded by shutting down its civilian airspace as Prime Minister Imran Khan called for negotiations with his Indian counterpart Narendra Modi, to ensure “better sense can prevail.”Tuesday’s pre-dawn strike by India was its first inside of Pakistan since the two nations’ 1971 war over territory that later became Bangladesh. Pakistan had said that Indian warplanes dropped bombs near the Pakistani town of Balakot but there were no casualties.The violence Wednesday marked the most-serious escalation of the long-simmering conflict since 1999, when Pakistan’s military sent a ground force into Indian-controlled Kashmir at Kargil. That year also saw an Indian fighter jet shoot down a Pakistani naval aircraft, killing all 16 on board.
