Intelligence agencies have warned that two suspicious Pakistani boats have left the port in Karachi and are on their way to either the coast of Gujarat or Maharashtra.

The input has provided the Navy and the Coast Guard with the latitude and longitude of the boats and also said that one of the boats is stuck in Pakistani waters after developing a technical snag. The second boat is also holed up close to the first one.

The Indian Navy and the Coast Guard have been put on alert regarding the movement of the two Pakistani boats making their way to India, according to local media reports.

The news comes a day after the Indian Coast Guard ship "Samudra Pavak" intercepted a Pakistani boat with nine crew members off the Gujarat coast on Sunday. The crew was taken into custody and then taken to Porbandar for further investigation.

"Preliminary information indicates the crew to be Pakistani fishermen. However, the boat and the crew members are being escorted to Porbandar for further probe," a statement issued by the Indian agencies said.

The crew members will be jointly interrogated by various agencies, while a case of intrusion will be registered at the Yellow Gate police station in Mumbai, the Times of India quoted defence sources as saying.

The Indian armed forces have been on high alert due to the possibility of retaliation from Pakistan's side to the surgical strikes carried out by the Indian Army on seven terror launch pads along the Line of Control on September 29.

The Ministry of Home Affairs issued an advisory to all the states directing them to deploy forces in sensitive areas, strategic installations, markets, religious places, especially the metro cities, to ensure security during the festive season.

Several ceasefire violations and infiltration bids have been foiled by the army since the strikes. Pakistan violated ceasefire in Gurdaspur city of Punjab and Poonch district of Jammu and Kashmir on Monday morning.

The border states of Punjab, Gujarat, Rajasthan and Jammu and Kashmir have also been put on high alert with people being evacuated and sent to safer locations.

Militants attacked an army camp in the Baramulla district killing one Border Security Force (BSF) jawan and injuring two others. Two other army personnel were also injured, while two terrorists were neutralised.
