The brother of British Iraq hostage Ken Bigley says sources in Kuwait believe his sibling is being transferred by hard-line extremists to another group.

Paul Bigley said in British radio interviews Monday that his sources tell him the new group is likely to demand a cash ransom, rather than make political demands.

Mr. Bigley said he believes it will now be easier to obtain his brother's release. He said he "would much rather be dealing with people talking money than ones holding a government to ransom."

The British government has cautioned that the reports of Ken Bigley's transfer, initially published in a Kuwaiti newspaper, are still unconfirmed.

Ken Bigley was kidnapped last month with two American contractors by the Tawhid and Jihad group led by Jordanian-born terrorist Abu Musab al-Zarqawi. The two Americans were beheaded soon after their abduction.
