Greek police find suspected guerrilla arms cache

Greek police detained seven people and found guns believed to belong to leftist guerrillas in houses in Athens and Volos in central Greece on Monday.A police official who declined to be named said the raids took place based on evidence of the suspects involvement in the Fire Conspiracy Cells guerrilla group.The official said more searches would be conducted in other locations in the country as part of the operation. Police detained five men and two women from the two houses that were searched in Athens and Volos, saying one of the men had two arrest warrants against him.The police official added that ballistic tests will be carried out to determine whether the weapons found had been used in prior guerrilla attacks. Greece has a decades-long history of leftist violence and some groups have sprung up or become more active since December 2008, when the killing of a teenager by police triggered three weeks of rioting and attracted global attention.The Fire Conspiracy Cells initially staged arson attacks but later turned to bombings. Their devices usually contain small amounts of explosives, not enough to kill. The group has said it was behind a wave of parcel bombs against embassies and foreign governments abroad in November last year.It claimed responsibility for a powerful explosion which damaged a court house in Athens in January this year.
