U-S officials say an al-Qaida leader believed to be the terrorist network's chief of operations in the Persian Gulf region is now in U-S custody.
The officials say Abd al-Rahim al-Nashiri was captured earlier this month in an undisclosed country.
Analysts say he is the highest-ranking al-Qaida operative captured since U-S and Pakistani authorities seized Osama bin Laden's operations chief Abu Zubaydah in Pakistan in March.
U-S officials say Abd al-Rahim al-Nashiri helped to plan the bombing of the U-S-S Cole in Yemen's Aden Harbor in October 2000. The attack on the warship killed 17 U-S sailors.
Officials also link him to the 1998 bombings of U-S embassies in East Africa.
U-S officials had recently said that a senior al-Qaida member had been caught, but declined to identify him.
