Kolkata - India's navy on Tuesday withdrew two warships from Kolkata's port, a spokesperson said, as the eastern city was placed on high alert for a possible "terror" attack.
The navy said the ships had withdrawn for "prior operational reasons", although a port official indicated they had been due to take part in an exhibition on Wednesday.
"They had come there as part of preparations for the navy week exercise and moved out of the port for some prior operational reasons," spokesperson DK Sharma told AFP.
"Like every year, the ships will return as and when the opportunity exists."
