An Indonesian man known as "Hambali," suspected mastermind of the Bali bombings and the more recent JW Marriott blast in Jakarta, has been captured.
"His capture is another important victory in the global war on terrorism and a significant blow to the enemy," said White House spokesman Mr Scott McClellan.
Suspicion over the August 5th car bomb attack on the JW Marriott Hotel, which killed 12 people and wounded 150, has focused on Jemaah Islamiah, the Southeast Asian militant Muslim network blamed for the Bali bomb blasts that killed 202.
Indonesia's police chief said yesterday officers had put under surveillance individuals who might be among militants suspected of carrying out the Marriott attack.
