A U.S. aircraft with 205 American Marine commandos on board was made to land on Sunday at Mumbai airport for allegedly violating the Indian airspace.

The chartered plane was on its way from Fujairah in Middle East to Bangkok, an airport official said. The aircraft was using a civilian call sign, officials said.

“A U.S. aircraft with 205 U.S. Marines on board, on its way from Fujairah to Bangkok, was forced to land in Mumbai while overflying Indian airspace as there was some confusion about its call sign,” a Mumbai International Airport Limited spokesperson said.

The aircraft landed at Mumbai airport at 7.52 am and has been parked at a remote bay, the spokesperson said adding, all passengers are on board.

Indian Air Force is looking into the issue, the spokesperson said.
