Alliance takes Tora Bora - but where is bin Laden?

Fears were growing tonight that Osama bin Laden may have eluded the coalition and tribal forces which successfully laid siege to the last remaining al-Qaida stronghold in Afghanistan.

Tribal forces declared victory in the battle for the Tora Bora area of mountainous eastern Afghanistan, saying they had killed more than 200 fighters and taken another 25 captive.
