LONDON (AP) — A British man accused of terrorist fundraising on Monday launched a High Court bid to halt his extradition to the United States, mirroring a similar move by radical cleric Abu Hamza al-Masri.

Babar Ahmad, 38, has been detained in Britain since 2004 on a U.S. warrant. He is accused of running websites used to raise money for terrorists, and of supplying terrorists with gas masks and night-vision goggles. He has not faced charges in Britain, but has been held without trial for the longest period of any British citizen detained since the Sept. 11, 2001, attacks.
