Mumbai, Sep 23 (PTI): Teams of elite anti-terror commando force NSG have been deployed in three locations in Mumbai and another team has been kept ready in Delhi to be flown if required after a group of men were spotted moving suspiciously near a naval base along Maharashtra coast.

Teams of National Security Guard, drawn from its Mumbai hub, pre-positioned at three locations in Mumbai and another team is on alert at NSG base in IGI airport in Delhi, official sources said.

Precautionary action taken in Mumbai to cut down reaction time in case of any emergency situation, sources said.

A high alert has already been sounded along the Maharashtra coast after the group of men were spotted moving suspiciously near a naval base at Uran in Raigad district, leading to multi-agency search operations by multiple agencies.

The alert comes four days after the terror attack in Uri in which 18 soldiers were killed.

Coastal security has been a top priority after the 26/11 attacks in Mumbai in which multiple locations in the city were targeted by Pakistani terrorists who landed using the sea route.

The fishing town of Uran is located across the eastern water front of the financial capital.
