Revolutionary Struggle has claimed responsibility for the attack.
Revolutionary Struggle:
The group, which espouses communism, has continued its anti-Western stance after the Cold War. November 17 bitterly opposes Greek participation in NATO. It also favors ousting U.S. military bases from Greek territory, severing Greece s ties with the European Union, removing the Turkish military presence from Cyprus , and launching an anti-capitalist popular uprising against the Greek middle and upper-classes. In December 2000, after killing a British general, the group released a communiqué defending itself against mounting public criticism by trying to appeal to populist, pro-Serb sentiments and urging Greeks to defy the governments counterterrorism efforts.
