A judge sentenced a Canadian man to 10 1/2 years in prison Thursday for plotting with a group of British Muslims to bomb buildings and natural gas lines in the United Kingdom. Momim Khawaja is the first person to be sentenced under Canadian anti-terrorism laws passed after the Sept. 11, 2001, attacks. He was convicted last fall of financing and facilitating terrorism. His case is considered to be the first major test of the anti-terrorism laws. The Canadian-born Muslim of Pakistani descent was accused of collaborating with Britons of Pakistani descent in a thwarted 2004 plan to attack a London nightclub, a shopping center, and electrical and gas facilities. Khawaja pleaded not guilty to all charges.
