WASHINGTON (APP) - The United States on Friday said Pakistan is striving to push back terrorists, who pose a threat to the Pakistanis's aspirations for a moderate life and with the shocking attack on the visiting Sri Lankan team of the popular sport tried to hit at the South Asian soul. A top US diplomat also renewed US commitment to cooperation with the key regional ally in fighting terrorism as the new administration moves forward to find an effective way forward in the Pak-Afghan region. Richard Boucher, Assistant Secretary of State for South Asia, praised the Pakistani policemen for their valiant struggle and sacrifice to save the touring Sri Lankan cricket team, calling them "heroes in the line of duty." He said the United States is ready to extend its cooperation to Pakistan and Sri Lanka in investigating the incident in Lahore but noted at the moment Pakistan has not needed the American help. "We are expressing condolences at the attack in Lahore, as the President Barack Obama did the other day, the Pakistani policemen were killed in Lahore in the attack on the Sri Lankan cricket team. Certainly, it is something that shocked us all," he said of the attack this week. He said the United States would see the Pakistani authorities to find out who perpetrated the attack. Questioned about the US offer for cooperation in investigation he replied: "We have close ties with the Pakistani authorities. But at this point I don't think there is any particular help identified at this point. The US offer for help is always there." "They (the terrorists) are going after, as you said, at the very soul of South Asia, the very heart of Pakistani people. So, I think, all of us understand that all these terrorists are threatening the aspirations the Pakistanis have to living a normal, moderate life. "I have not a clue why anyone would want to attack targets, people like these. What I do know is that Pakistani security services are fighting valiantly, and we saw in the attack in Lahore seven of them died trying to protect the cricket team. That's what they are sworn to do, what they are called upon to do. But they are our heroes who died in the line of duty." Boucher said the United States is concerned at the recent wave of terrorist attacks in Pakistan including those on a "Sufi" shrine in Peshawar and on the Sir Lankan cricket players but expressed encouragement with the country's determination to fight back. "There are a lot of concerns. But I also know that there are a lot of people fighting back. We just had the Pakistani and Afghan delegations here working with us closely on the review of the policy. We are looking at how we can put together a common strategy to meet the terrorist threat, provide economic opportunity, good governance for people in both Pakistan and Afghanistan. "On my last trip, I visited Marriott in Pakistan and the Taj Palace in Mumbai. You see people all of these regions, they are rebuilding, they are determined to provide a better life to people, they are determined to fight back in all kinds of ways, whether it is rebuilding hotels, improving government, or actually like the Pakistani soldiers in military, using their arms. So, I think there are a lot of people who are trying to push back terrorists and we want to work with that. The US diplomat would not put any timelines on the counterterrorism efforts but said these have to go on. "I cannot give a timeline but you have got to pushing back in all kinds of ways." He said he did not know of the terrorists' links to Sri Lankan Tamil Tigers, who are fighting the Sri Lankan government. Responding to a question in the context of cooperative spirit and understanding shown by the Pakistani and Sri Lankan leaders, he said the United States would support regional cooperation and a regional approach to tackling the problem. "I think we have all seen that terrorism is a threat to all of us and all kinds of terrorists are a threat to all of us, whether they are the Taliban or the Tamils." He said terrorists undermine the region and it is important to take a regional approach. In this context, he recalled that during his visit to Bangladesh he talked to Prime Minister Sheikh Hasina Wajid about her proposal to have a regional counterterrorism group. "That sounded like a good idea to us. We will help countries in the region. We will find ways to cooperate against terrorism and of course any we can support, we will try to do so." Boucher said he also met with the Mayor of Karachi and talked to him about efforts in Karachi to give people good lives in that city.
