Authorities in Indian-controlled Kashmir have stepped up security apparatus and sounded caution Saturday, ahead of the Indian Republic Day that falls on January 26 every year.

The steps have been taken to thwart possible attempts by suspected militants to disrupt official celebrations, police said.

"For the past few days the security has been beefed up in the region to ensure the official celebrations are held without any disruption," said a senior police official in Srinagar, the summer capital of Indian-controlled Kashmir.

India policemen and paramilitary troopers of India's Central Reserve Police Force (CRPF) deployed on roads were seen checking vehicles and frisking pedestrians in twin capital cities of Srinagar and Jammu.

Policemen carrying metal detectors were seen checking roadsides and vehicles for explosives.

In Srinagar, the security agencies have cordoned off the Bakhshi Stadium -- the main venue for the Jan. 26 function. A multi-tier security system has been put in place with sharp shooters taking positions atop houses adjacent to the stadium to thwart any militant attack.

The paramilitary troopers have pressed in sniffer dogs to carry out searches for explosives in and outside the stadium.

The roads leading to Bakhshi Stadium are under strict vigil. Barricades and concertina wires have been placed on the roads to restrict movement of people and vehicles.

Mobile bullet proof bunker vehicles are also parked in the middle of some roads to sabotage any attack.

The security agencies have activated all the installed Closed Circuit Television Cameras (CCTVs) in Srinagar to monitor the movement of people and keep an eye on untoward incidents.

Unprecedented security arrangements have also been made in Jammu, the winter capital.

The Moulana Azad Memorial Stadium -- the main venue for official function in Jammu -- too has been cordoned and kept under tight surveillance.

The Republic Day in India marks the adoption of the constitution of India. The main function will be held in national capital New Delhi, where India's military, navy and air force will display their skills and military might.

A guerrilla war aimed at putting an end to Indian rule is going on in the region between militants and Indian troops.

Meanwhile, separatist groups have called for a complete shutdown in the region on the eve of Jan. 26.

Reports said India's federal government has sent an advisory to all states to tighten security in sensitive locations in wake of intelligence inputs suggesting militant groups might try to cause disturbance.

India's Home Ministry has reportedly directed Indian-controlled Kashmir and northeastern states to deploy additional forces in sensitive locations to thwart possible attacks.
