The leader of the terrorist network al Qaeda has burst back onto the scene just days before the US presidential election. In a videotape first broadcast sent to an Arabic TV station, the militant leader criticises George W. Bush and accuses him of deceiving the American people.He threatens new September 11 style attacks and explains that the reasons the assault was launched have not changed. The tape provides one of the clearest claims yet of responsibility for the attack in 2001. On the tape, bin Laden adds that 9/11 would not have been so severe if Bush had been more alert. The tape appears to have been recorded recently as bin Laden alludes to the upcoming election. He says: “Your security is not in the hands of Kerry or Bush or al Qaeda. Your security is in your own hands and each state which doesn’t harm our security will remain safe.” The al Qaeda leader explains he had first thought of attacking the United States after the 1982 Israeli invasion of Lebanon. The Arabic news channel Al Jazeera received the tape on Friday but did not say how. If it is proven to be genuine, it provides clear evidence that Osama bin Laden is still alive and apparently in good health.
