Airline Vistara halts service to north Indian cities amid tensions

Indian airline Vistara said on Wednesday flights to and from four cities in northern India are on hold as tensions between nuclear-armed neighbours India and Pakistan escalate.

"Due to airspace restrictions, flights to and from Amritsar, Srinagar, Chandigarh and Jammu are currently on hold," Vistara, a joint venture between India's Tata Sons Limited and Singapore Airlines Limited said in a tweet.

India said its warplanes struck a militant training camp inside Pakistan on Tuesday, raising the risk of conflict between the two countries. (Reporting by Sudarshan Varadhan; editing by Darren Schuettler)
