[Verjee:] Welcome back. You're watching an hour of world news on CNN INTERNATIONAL. Londoners' nerves are on edge with events unfolding rapidly in the city's terror alert. Police have released photos of four suspects in Thursday's bungled bombings. The pictures come from closed circuit television in the transit system. Authorities are asking the public's help in identifying the men. Meanwhile, police fatally shot a man at the Stockwell Underground station on Friday. Police say the shooting was directly linked to the ongoing investigation. But it's unclear if the man was one of the suspects whose pictures are being shown. Police are searching at least three location in London as part of their investigation. One area is West London, where police have cordoned off Harrow Road. In other incidents, an East London mosque said police called after receiving a bomb threat. The mosque has since reopened. In a broadcast interview in the United States, Pakistan's president, Pervez Musharraf, says Britain should try and solve its own problems at home and not blame Pakistan for influencing the July 7th suicide bombers. With us now to discuss some of those tensions between Britain and Pakistan is Islamabad's ambassador to the U.N., Munir Akram. Mr. Ambassador, how tense is it, pointing fingers?
[Munir Akram, Pakistani Ambassador To U.n:] Well, I think that we must be clear that we have good cooperation with Britain, with the United States, and with all the countries who are involved in the war against terrorism. At the same time, the war against terrorism is both local as well as global. And I think each one of us has to do its part in fighting this war on terrorism. So when something happens somewhere, the focus has to be on dealing with the problem there rather than externalizing it.
[Verjee:] Let's talk about Pakistan's part here. There have been more than 300 arrests since the crackdown on militants. Are any of those that have been arrested in Pakistan directly linked to the London bombings?
[Akram:] No, not as far as we know. We are cracking down because we need to do it. Whenever we have information, we crack down, we round up people, we interrogate them, and we find out what the connections are. But so far no direct connection has been established. And we are doing it for our own purposes, for our own role in the war against terrorism to prevent extremism and terrorism in our own society.
[Verjee:] A key British Muslim al Qaeda suspect by the name of Haroun Rashid Aswad, is he in Pakistani custody?
[Akram:] Not as far as I know. And I don't think that we know who this man is, but we do not know whether he's part of those who have been rounded up, but I don't know whether he's in Pakistan or in Pakistani custody.
[Verjee:] There were reports in the Pakistani local papers that he was taken into custody in Lahore earlier this week during the crackdown on madrassas. So no knowledge of that?
[Akram:] No, I don't think that this has been established. These are perhaps rumors but we are in the process of interrogation and we are doing it in our own context.
[Verjee:] Is that man, Haroun Rashid Aswad, already on a Pakistan watch list? Has he been on one?
[Akram:] I'm afraid I'm not in a position to tell you whether he is or not, but we certainly can check that. I suspect that if he's on an international list, he will be on our list.
[Verjee:] How many people do British investigators want arrested or investigated in Pakistan? What have they asked?
[Akram:] Well, the cooperation with Britain is ongoing and we are responding to whatever requests we receive. And this is an ongoing process, this is a daily process, before and after the London bombing. But in this case, we certainly also hope that Britain will do its part in restraining, if you will, those extremist organizations who are operating freely in Britain.
[Verjee:] President Pervez Musharraf announced a string of new measures cracking down on militants, tightening reins against extremist schools, particularly that preach hatred. How can we be sure that this isn't just a one-off thing that has been done in Pakistan under pressure since the terror attacks in London and that this may not just ease off at some point down the road?
[Akram:] You must understand that we are acting for ourselves to eradicate terrorism and extremism from our own society. President Musharraf has himself been attacked twice by these extremists and terrorists. So we have to do it for our own society. We are a country that's growing rapidly. We have great hope and aspirations and we must do it for ourselves. And we do not act under pressure. And certainly there is no pressure on us to act. We are doing it on our own, for our own sake, and we are an active leading player in the war against terrorism.
[Verjee:] Pakistan's ambassador to the United Nations, Munir Akram, thank you.
[Akram:] Thank you.
[Holmes:] All right. Let's take a look at some stories making news in the United States. Amid the heightened tension on transit systems in the U.S. and Europe, American lawmakers are focusing on the anti-terrorist Patriot Act. The House of Representatives voted to extend the law indefinitely while a Senate committee approved its version of an extension. But senators called for a re-examination of controversial provisions that allow federal agents to use roving wiretaps and search library and medical records. The White House is turning its attention away from Supreme Court nominees and the controversy surrounding the president's top aide, and back to his campaign for Social Security reform. President Bush is addressing a crowd made up largely of senior citizens in Atlanta, Georgia. His proposed overhaul of the Social Security system has run into widespread opposition. Two airline pilots who got behind the controls after a night of heavy drinking have been sentenced to prison. The judge didn't hide his disdain, saying, what were you thinking of? The two were drunk when they stepped into the cockpit of a Phoenix-bound America West jetliner in 2002. They were arrested before the plane took off. One was sentenced to five years behind bars, the other, two-and-a-half. And we will be back after this break.
