Police fear Nov. 17 link in Greek blasts

A police spokesman said the bombs went off about 10 minutes apart, with the second explosion injuring the officer as he went to investigate the first. The courts were closed at the time.

"The explosions around 3 a.m. (0000 GMT) damaged parts of building seven of the courts and slightly injured the officer who rushed to the scene of the first blast," he told reporters.

No one has claimed responsibility for the explosions, but police said they could be a response to Thursday’s testimony in the trial of a Greek Marxist accused of being the founder of the November 17 guerrilla group and 18 other suspected leftist guerrillas.

Before being broken up last year, November 17 killed 23 British, Turkish and U.S. diplomats as well as Greek politicians and businessmen over 27 years.

"It may well be in response to Alexandros Giotopoulos’ testimony. It may be an act of solidarity for the terrorists on trial," one police official said.

The group had been considered the biggest domestic security threat to next year’s Athens Olympics. Giotopoulos, facing 1,000 charges for his participation in November 17, has denied being the leader of the group.
