An extreme leftist group which first emerged two years ago claimed responsibility for three bomb explosions outside the premises of construction firms in Athens over the last eight months, in a declaration made public yesterday. Popular Revolutionary Action said it targeted the companies because they made «exorbitant gains» during building work for the Athens Olympics at the expense of the working class and vital infrastructure projects, such as the building of schools. The group claimed it placed small bombs outside the premises of Technical Olympic in the southern suburb of Alimos last December, at the offices of J&P Avax in Ambelokipi in May and outside a work site of the Aktor construction firm in Petralona, near the city center, this month. In all three cases, the bombs were ineffective and caused little damage and no injuries. The group was one of at least two that emerged after members of November 17 and Revolutionary People’s Struggle (ELA) were caught in 2002 and it first came to light a year later when it tried to attack the offices of the US insurance company Alico in central Athens. «The struggle continues,» the group concluded in its declaration, sent to the daily Eleftherotypia.
