ISLAMABAD - Pakistan on Monday expressed its serious concern over the Indian Prime Minister Manmohan Singhs remarks that possible terrorist attacks in India were being planned on Pakistani soil. We have noted the reported comments made by the Prime Minister of India today in which he expressed apprehensions about terrorist attacks being planned in Pakistan against India, said the foreign office spokesman, Abdul Basit. The Deputy High Commissioner of India was called to the Foreign Office by Director General (South Asia) on Monday. He was conveyed that the Indian Prime Ministers remarks warrant serious and prompt attention, he said. He said the government of Pakistan would like to extend its fullest cooperation to pre-empt any act of terror. Terrorism is a common enemy. Pakistan has itself been a victim of terrorism, he said. At Sharm El Sheikh, both sides had agreed that the two countries would share real time, credible and actionable information on any future terrorist threats, he said. In all sincerity, we would request India to share information that they have and for our part we stand ready to cooperate fully in pre-empting any act of terror, Basit said. He said the terrorism could only be combated by serious, sustained and pragmatic cooperation. We wish to renew our offer of cooperation to India in this regard, he said. Reuters/AFP add: Indias prime minister said on Monday there was credible information that Pakistan-based militant groups were planning fresh attacks on India. Manmohan Singhs statement was the latest attempt by India to pile more pressure on Pakistan to act against anti-India militants that New Delhi blames for last Novembers Mumbai attacks. Coming to specific challenges, cross-border terrorism remains a most pervasive threat, Singh told a conference on national security attended by provincial chief ministers. There is credible information of ongoing plans of terrorist groups in Pakistan to carry out fresh attacks. After the Mumbai attacks, we have put in place additional measures. There is need for continued utmost vigilance, added Singh, who also pointed to the threat posed by left-wing militants in the east of the country. India has boosted its security to prevent assaults after the Mumbai attacks in November, in which gunmen killed 166 people. All states need to actively share intelligence information to avert any terror attack, he said. Indias intelligence-gathering techniques were severely criticised after their collective failure to thwart the bloody Mumbai attacks. Singh also said Pakistan-based groups fighting Indian rule in Kashmir region had stepped up efforts to send their militants across after a period of relative calm in the region. The areas of operation of these terrorists today extends far beyond the confines of Jammu and Kashmir and covers all parts of the country, the prime minister said. He said though the level of violence had gone down in Kashmir during the past few years when India and Pakistan began their peace talks in 2004, there has been a surge in the incidence of infiltration attempts by the Pakistan-based militants. The infiltrators appear more battle-hardened, better equipped and in possession of sophisticated communications. There are also signs of a revival of over ground militant activities...All this shows that efforts to disturb the current status quo has not been given up, Singh said. Indias Home Minister Palaniappan Chidambaram told the summit that the country has faced no terror strike after the Mumbai attacks but it does not mean that the threat of terror has vanished or receded. The prime minister also said India faced another serious challenge from left-wing extremism, namely Maoists who have inflicted heavy casualties on security forces. Indias Maoists, also known as the Naxals, say they are fighting for the rights of neglected tribal people and landless farmers. They are now active in more than half of the countrys 29 states - particularly in the east, the poorest part of India. Estimates of their numbers nationwide range between 10,000 and 20,000, but little is known about their shadowy leadership. To deal with the Maoist crisis, Chidambaram announced a multi-pronged strategy at the summit. We will talk, we will act, we will restore order and we will undertake developmental activities in Naxal-hit areas, he said. Monitoring Desk adds: Indian Prime Minister Manmohan Singh stressed on the need for continued utmost vigilance while saying cross-border terrorism remains a most pervasive threat, reported Indian media. While acknowledging that the situation in Jammu and Kashmir has improved, the PM said infiltration bids in the state have increased. Noting that there were signs of revival of over-ground militant activities, he said attempts were being made to link isolated and unconnected incidents like the ones in Shopian, Sopore and Baramulla to create an impression of a groundswell of anti-India feeling. All this shows that efforts to disturb the current status quo have not been given up. Fortunately, the annual Amarnath Yatra passed off without incident, a tribute to the secular character of Jammu and Kashmir, Singh said. In an apparent reference to the Mumbai terror attacks, Singh stressed on the need to guard our maritime borders. He also exhorted the states to extend full support to the National Investigating Agency, set up in the aftermath of the 26/11 strikes.
