MONTREAL — Air Canada says it has suspended service to India as tensions mount between that country and Pakistan.

An airline spokeswoman says a flight en route to Delhi turned back over the Atlantic Ocean this morning and has headed back to Toronto.

A second Air Canada flight from Vancouver to Delhi today was also cancelled.

According to media reports Pakistan has closed its airspace.

Spokeswoman Isabelle Arthur says the airline has implemented a goodwill policy for affected customers and is monitoring the situation in order to resume service once it normalizes. The airline has posted travel advisories for both Delhi and Mumbai on its website, citing Airspace Closure. The advisories are valid for flights on Feb. 27 and Feb. 28, and allow passengers to change their travel plans without incurring change fees.

Pakistan 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 in this century.

Air Canada operates daily service from Toronto and Vancouver to Delhi and four times weekly between Toronto and Mumbai.
