Air India's official Twitter account was hacked late last night for many hours before being restored, the airline said today. Messages in Turkish language were posted on the official Twitter handle @airindiain to mislead passengers, an Air India spokesperson said, adding all the malicious contents posted on the handle have been removed. "Air India immediately swung into action and took up the matter with the Twitter authorities. All malicious content was removed on a war-footing. It is hoped that normalcy would be restored soon, " the spokesperson said in a statement. All Air India flights are operating as per schedule, he said. "Passengers are requested to ignore any misleading and mischievous communication on our operations," the spokesperson added. One of the posts by the hackers read, "Last minute important announcement. All our flights have been cancelled. From now on, we will fly with Turkish Airlines'. Air India has 1,46,000 followers on Twitter.
