ISLAMABAD - Pakistan Armed Forces Friday restricted leave of their personnel as part of defensive measures to ward off Indian threat of war. A senior security official told TheNation that Armed Forces had taken minimum defensive measures as part of necessary preparations. "Limited troops have been pulled back from the snowbound areas as well as from those where there are no operations going on", the official said. He also confirmed necessary restrictions on leave of the armed forces personnel. He did not elaborate when asked to identify the regions wherefrom the troops had been withdrawn. However, reliable sources in the Federally-Administered Tribal Areas (Fata) confirmed the movement of troops. Sources said that Pakistan Army would withdraw about 30,000 troops to redeploy them along Pakistan's border with Indian. It was learnt that Pakistan Army had moved its infantry troops and re-deployed them on the Indian border. A Defence Ministry source said that authorities had noticed the movement of Indian troops towards the border near Lahore, and that they believed India had also cancelled military personnel leave. Meanwhile, Pakistan Air Force and Pakistan Navy have also stepped up operational preparedness to meet any eventuality. Pakistan Air Force has enhanced vigilance of the strategic assets of the country, while Pakistan Navy has also taken necessary defensive measures. According to ISPR, Commander Pakistan Fleet Rear Admiral M Asif Sandila, Friday visited the deployed Fleet units to assess their operational readiness. He expressed his satisfaction at the operational and material readiness of PN Fleet and reiterated that Pakistan Fleet was ready to respond to any challenge whenever called upon and would uphold the trust reposed by the nation. The Fleet Commander stressed that though Pakistan was a peace-loving nation, yet in case of any misadventure against the maritime interest of the country, the same would be responded in a befitting and resolute manner. He stressed upon the fleet units to maintain the present state of high preparedness to thwart enemy's aggressive designs. Relations between the South Asian neighbours have been badly strained since the Mumbai attacks, for which New Delhi has been blaming Pakistan-based militants, while Islamabad says India has not provided any evidence in this regard. Agencies add: Pakistan has cancelled leave for "operational" armed forces personnel and redeployed troops to the Indian border amid simmering tensions with New Delhi, a military official said Friday, in a dramatic escalation of tensions with New Delhi in the wake of the Mumbai attacks. Chief military spokesman Maj-Gen Athar Abbas declined to comment, but a senior Defence Ministry official confirmed some troops were being withdrawn from the restive northwest and sent to the Indian border. Senior Pakistani defence and security officials told AFP thousands of troops were being moved from the restive northwestern tribal areas bordering Afghanistan to the east of the country along the Indian border. "We do not want to create any war hysteria but we have to take minimum security measures to ward off any threat. Leaves of all operational personnel of the armed forces have been cancelled as a defensive measure," he told AFP. Another senior security official told AFP the new deployments on the Indian border were not in "significant numbers but only in areas opposite the points where India is believed to have brought forward its troops". The Defence Ministry official said authorities had noticed the movement of Indian troops towards the border near Lahore, and that they believed India had also cancelled military leave. A senior military official said that the decision to sharply restrict leave for soldiers was taken "in view of the prevailing environment," namely the deteriorating relations with India since the Mumbai attacks. He added that the Pakistani Air Force was "vigilant" and "alert" for the same reason. Any significant cut in troop numbers by Pakistan along its porous western border would likely spark concern in Washington and other Western capitals, as it could open the door to more militant attacks on foreign forces in Afghanistan. Airstrikes against militants in the Swat and Bajaur regions had been scaled down as some of the airpower had to be redeployed to the country's eastern border, a senior Pakistani military official told the BBC Urdu service. The Pakistan Army has postponed an impending ground operation against militants in the Khyber tribal region. Pakistan deployed an extra 20,000 troops to its border with India. In tandem with the military moves, civil defence authorities have launched a public awareness campaign in Muzaffarabad, the capital of Azad Jammu and Kashmir. "We have launched an awareness campaign in Kashmir to prepare people for self-defence and response in an emergency situation, amid the looming threat of possible Indian aggression," civil defence official Ghulam Rasool Nagra said. The military also moved fresh troops to the Line of Control and the international border with India to protect 'vital points' and a virtual security alert put into effect, military sources were quoted as saying by a private TV channel. Army had moved its 10th Brigade to Lahore and ordered the 3rd Armoured Brigade to head towards Jhelum alleging a concentration of Indian troops on the border. The Army's 10th and 11th Divisions have also been put on high alert and troops moved to forward posts on the border facing Rajouri and Poonch sectors. These troops reinforcement are in addition to the formation already deployed in the Pakistan Occupied Kashmir, Sialkot and Lahore. "Leave has been cancelled because of the situation. All soldiers have been asked to report to duty," said another military official who declined to be identified, while talking to a foreign news agency. Military spokesman was not available for comment but several soldiers confirmed that orders had gone out calling soldiers back from leave. Two intelligence officials said the Army's 14th Division was being redeployed to Kasur and Sialkot, close to the Indian border. They said some 20,000 troops were on the move. The officials spoke on condition of anonymity because of the sensitivity of the situation. An American news agency reporter in Dera Ismail Khan, a district that borders South Waziristan, said he saw around 40 trucks loaded with soldiers heading away from the Afghan border. A senior security official refused to comment directly on Friday's troop movements, but said, "Necessary defensive measures have been taken, they are in place and armed forces are prepared to tackle any eventuality." Another unnamed Pakistan Army official told CNN that the Arm has been taking precautionary measures to safeguard borders in the face of mounting military threats from India over the Mumbai attacks. "Naturally, you have to take certain steps to stem that expected tide of Indian operations," he said, "You can't fight on both fronts so we have redeployed certain military elements from the western border to the northern border to meet Indian operations." The official said that while Pakistan has tolerated US missile strikes from Afghanistan into Pakistan, he believes the government and public would not stand for an Indian incursion.
