The attacker did not try to penetrate even the first of several U.S.-manned security checkpoints at Bagram, instead detonating himself among a group of Afghan workers outside the base. Dadullah insisted bin Laden was alive and well. “Thank God, he is alive. We get updated information about him. Thank God, he planned operations in both Iraq and Afghanistan,” he told Al-Jazeera in excerpts that were translated into Arabic.160Want local news?Sign up for the Localist and stay informed Something went wrong.

Deputy White House press secretary Dana Perino said it was “an interesting claim but … I haven’t seen any intelligence that would support that.” A U.S. counterterrorism official, who spoke on condition of anonymity because of the information’s sensitivity, said al-Qaida would likely have used more than a single explosion outside the base’s main gate if it were targeting Cheney. In addition, the official said, it takes bin Laden significant time to communicate from where he is hiding. That wouldn’t offer him the flexibility to order an attack on Cheney, whose stop at Bagram was kept secret in advance of his arrival, the official said. The U.S. military had said previously that it was unclear whether the Taliban knew about Cheney’s visit or whether the timing of the attack was a coincidence. The Feb. 27 bombing killed 20 Afghan civilians, a U.S. soldier, a U.S. contract worker and a South Korean soldier outside Bagram while Cheney was meeting with officials inside the base. The Taliban claimed the attack was aimed at Cheney, but officials said it posed no real threat to him. CAIRO, Egypt – A top Taliban commander said al-Qaida leader Osama bin Laden was behind the February attack outside a U.S. military base in Afghanistan during a visit by Vice President Dick Cheney, according to an interview shown Wednesday by Arab broadcaster Al-Jazeera. Bin Laden planned and supervised the attack that killed 23 people outside the Bagram base while Cheney was there, said Mullah Dadullah, the Taliban’s main military commander in southern Afghanistan who has had close associations with al-Qaida. “You may remember the martyr operation inside the Bagram base, which targeted a senior U.S. official. … That operation was the result of his wise planning. He (bin Laden) planned that operation and guided us through it. The operation was a success,” Dadullah told Al-Jazeera. He did not say how he knew bin Laden planned the attack, and it was not clear when the interview took place.
