Chennai /Â AFP
India on Saturday stepped up a major search operation for an air force plane that disappeared over the Bay of Bengal the day before with 29 people on board, as the defence minister headed to the region.
The AN-32 military transport plane was on a routine flight from the southern city of Chennai to Port Blair, capital of the remote Andaman and Nicobar islands, on Friday morning when it vanished from radar screens.
Twenty-one of the passengers on board were defence personnel, including six crew members, while eight others worked for the military in non-uniform roles, an IAF source said.
On its official Twitter account the Indian navy said 18 navy and coastguard ships were now deployed in the search operation, along with six aircraft and a submarine.
“#SAROps 18 Naval & ICG ships (+1sm) deployed with various aircraft… to locate missing AN 32†the navy tweeted.
