I understand that Muslims must warn their enemies of impending attacks. According to Christiane Amanpour, Osama has been given religious approval "by a young cleric in Saudi Arabia authorizing al Qaeda to "use nuclear weapons against the United States ... capping the casualties at 10 million."
They are talking about the next attack on the U.S., reportedly involving nuclear suitcase bombs in 7 cities, flown over the Mexican border in a hijacked crop duster and already in place, which will "reduce America to ashes."
And more specifically, from here, an interview with Abu Dawood (highlighting is mine)
"Mr. Mir interviewed Dawood (no specific date indicated) at the tomb of Sultan Mehmud Ghaznawi, on the outskirts of Kabul. Dawood and the al Qaeda leaders who accompanied him sported short beards and were dressed casually, for disguise. The al Qaeda commander had contacted Mir by cell-phone to arrange the meeting. The contents of the encounter are as follows:
Q: How did you have my local mobile number?
A: We watched you on Geo TV walking in the mountains near Kabul with British troops. You were embedded with our enemies. We were sure that you are staying in one of the few hotels or guest houses in Kabul. We were looking for you in Serena and Intercontinental hotels, but then some Taliban friends informed us that they had your phone number and you might visit them in Zabul [an Afghani province]. We got your number from Commander [Muhsen] Khayber. [Khayber was responsible for a homicide bombing in Casablanca that killed 32 people]. Don't worry about that. We will not make any harm to you. We just want to warn you that you better don't take any rides in the tanks and humvis of the Western Forces; they are not safe for any journalist in Afghanistan.
Q: Thanks for your concern; can I know your name?
A: Yes my name is Abu Dawood, if you remember, we have already met in Kunar two years ago, but at that time I had a long beard, now I have a small one. You were there in the mountains, close to Asadabad [a small village in the Kunar province of eastern Afghanistan] and you met some Al Qaeda fighters. I was among them.
Q: OK. I just want to say that I am a journalist, I have to speak to both sides of a conflict, for getting an objective view and that is why I was traveling with the British troops; now I am sitting with you and that is my real job. I have interviewed Osama bin Laden as well as Condoleezza Rice, General Pervez Musharraf and President Hamid Karzai of Afghanistan. I hope you will appreciate my objective approach?
A: You have claimed to be objective, but you and your TV channel have always given much time to the propaganda of our enemies. Anyhow, it was our moral responsibility to warn you that you better try to avoid traveling with the British, American, Canadian, French, Spanish and Italian troops in Afghanistan, we will target all of them, we don't want that people like you suffer by our attacks, it is not good for you, and at least you should not be killed with the enemies of Islam. I am sure, brother Khayber have informed you that the Taliban will launch a big operation against the Crusader Forces, in the holy month of Ramadan; don't come to Afghanistan in Ramadan. You will see a lot of fadaee amalyat ["suicide bombings"] in the coming days, Kabul will become a graveyard of NATO and ISAF.
Q: Yes Khayber told me about the "Badar Operation" in Ramadan. I think you are an Afghani but you are not a Talib, are you a member of Al Qaeda?
A: You are right. But we are with the Taliban, just helping them, fighting under their command. Every Al Qaeda fighter can become a Talib, but every Talib cannot become Al Qaeda.
Q: So where is Sheikh Osama bin Laden?
A: I don't know exactly, but he is still in command of Al Qaeda, and he is in contact with his Mujaheddin all over the world.
Q: Why there was no new video statement from him, in last two years?
A: Because the CIA can feed his fresh picture to the computers fitted on their Predator planes, and these planes can get him, like Nek Muhammad or Akbar Bugti. But he has released many audio messages this year. Listen to him carefully. Don't underestimate his warnings. America is playing with the security of Muslims all over the world, now it is our turn again. Our brothers are ready to attack inside America. We will breach their security again. There is no timeframe for our attack inside America; we can do it any time.
Q: What do you mean by another attack in America?
A: Yes a bigger attack than September 11th 2001. Brother Adnan [el Shukrijumah] will lead that attack, Inshallah.
Q:Who is Adnan?
A: He is our old friend. The last time, I met him in early 2004, in Khost. He came to Khost from the North Waziristan. He met his leaders and friends in Khost. He is very well known in Al Qaeda. He is an American and a friend of Muhammad Atta, who led 9/11 attacks five years ago. We call him "Jaffer al Tayyar" ["Jafer the Pilot"]; he is very brave and intelligent. Bush is aware that brother Adnan has smuggled deadly materials inside America from the Mexican border. Bush is silent about him, because he doesn't want to panic his people. Sheikh Osama bin Laden has completed his cycle of warnings. You know, he is man of his words, he is not a politician; he always does what he says. If he said it many times that Americans will see new attacks, they will definitely see new attacks. He is a real Mujahid. Americans will not win this war, which they have started against Muslims. Americans are the biggest supporters of the biggest terrorist in the world, which is Israel. You have witnessed the brutality of the Israelis in the recent 34-day war against Lebanese civilians. 9/11 was a revenge of Palestinian children, killed by the US-made weapons, supplied to Israel. The next attack on America would be a revenge of Lebanese children killed by US-made cluster bombs. Bush and Blair are the Crusaders, and Muslim leaders, like Musharraf and [Afghani President Hamid] Karzai are their collaborators, we will teach a lesson to all of them. We are also not happy with some religious parties in Pakistan and Egypt, they got votes in the name of Mujaheddin, and then, they collaborated with Musharraf and [Egyptian President] Hosni Mubarak. Now look at all of them, Musharraf and Karzai don't trust each other, the CIA and ISI don't trust each other, all the hypocrites and enemies of Mujaheddin are suspecting each other; this help to us is coming from Heavens. Allah is with us.
Q: But if you attack inside America again, then Muslims living in America will face lot of problems, why would you like to create new problems for your brothers and sisters?
A: Muslims should leave America. We cannot stop our attack just because of the American Muslims; they must realize that American forces are killing innocent Muslims in Afghanistan and Iraq; we have the right to respond back, in the same manner, in the enemy's homeland. The American Muslims are like a human shield for our enemy; they must leave New York and Washington.
Q: But your fighters are also using the American Muslims as their shield, if there are no Muslims in America, then there would be no Al Qaeda, may be the Americans would feel safer?
A: No, not at all. We have a different plan for the next attack. You will see. Americans will hardly find out any Muslim names, after the next attack. Most of our brothers are living in Western countries, with Jewish and Christian names, with passports of Western countries. This time, someone with the name of Muhammad Atta will not attack inside America, it would be some David, Richard or Peter.
Q: So you will not attack America, while Muslims are there?
A: I am not saying that, I am saying that Muslims must leave America, but we can attack America anytime. Our cycle of warnings has been completed, now we have fresh edicts from some prominent Muslim scholars to destroy our enemy, this is our defending of Jihad; the enemy has entered in our homes and we have the right to enter in their homes, they are killing us, we will kill them.
