A right-wing extremist has gone on trial in Germany for a bombing more than 17 years ago that injured 10 recent immigrants from eastern Europe, including six Jews.

The 51-year-old man, whose name wasn't released in accordance with privacy laws, was considered a suspect after the July 2000 bombing in a Duesseldorf subway station, but authorities couldn't find enough evidence for a case.

That changed after he allegedly confessed to a fellow prisoner four years ago when he was incarcerated for another crime.

The suspect is accused of 12 counts of attempted murder for allegedly detonating a bomb remotely near the group of immigrants on their way home from German language lessons. He told the Duesseldorf state court Thursday that he was home at the time of the attack.
