(KUNA) -- Air marshals have been deployed on selected flights in India for passenger safety following threat reports from the country's intelligence agencies after Tuesday's serial blasts in Mumbai and Srinagar. "We have deployed air marshals today. Some more security systems are already in place," Indian Civil Aviation Secretary Ajay Prasad told reporters in Delhi Thursday, adding that intelligence reports warn of threats at some tourist destinations in India.He said while most flights to Indian-administered Jammu and Kashmir and certain sectors in India's Northeast will have these commandoes. The Aviation Ministry had also decided to set up some new security procedures at airports and instructions issued to the concerned agencies, Prasad said. "There would be significant changes in security measures at airports. We have deployed dog and bomb disposal squads. Emphasis will be on using more equipment and technology rather than manual searching," Prasad said. "The measures are being taken up because some reports have been received by the security agencies that some important airports and tourist destinations in the country are under threat," he said.
