Greek police arrested seven people suspected of belonging to one of the country's most militant guerrilla groups and taking part in bomb attacks, officials said on Sunday, Reuters reported. The arrest was a major strike against the urban guerilla group Revolutionary Struggle, which has stepped up attacks against police, public buildings and businesses since riots that paralysed Athens in December 2008. "They have been arrested and will be led to the prosecutor on charges of participating in a terrorist organisation," police spokesman Thanassis Kokkalakis told a news conference. Kokkalakis said police found a wealth of evidence at the residence of two of the people arrested, including a hard disk which had pamphlets claiming past attacks by Revolutionary Struggle as well as handwritten texts about past and intended "terrorist" attacks. Revolutionary Struggle emerged in September 2003, about a year after the capture of the deadly urban guerrilla group November 17. The group attempted to kill a minister in 2006 and launched a rocket-propelled grenade against the U.S Embassy in Athens, in 2007, causing minor damage and no injuries. It reappeared weeks after the police shooting of a teenager in December 2008, claiming responsibility for shooting at riot police guarding the culture ministry, which left a 21-year old officer seriously wounded. Police raided dozens of houses over the weekend, officials said. -- SPA
