Indonesia urged Washington on Friday to provide access to a militant linked to the 2002 Bali bombings after US President George W. Bush said he had been transferred to Guantanamo Bay. The Indonesian-born militant, known as Hambali, was arrested in a 2003 US-led operation in Thailand. "Indonesia has repeatedly asked for the whereabouts of Hambali. This announcement has given us clarity. We welcome the certainty of his existence," Indonesian foreign affairs spokesman Desra Percaya told a news briefing. Indonesia has in the past asked for access to question Hambali, who is suspected of playing a key role in the Bali bombings and other attacks, but Washington has only given Indonesian investigators filtered information from him and barred direct contact.
