The Piraeus office of Greece’s tallest member of Parliament was the target of a hand grenade attack yesterday afternoon by an obscure terrorist group whose only other known strike was the detonation of a bomb outside a Greek insurance company’s offices earlier this month. Socialist PASOK MP Panayiotis Fassoulas, a 39-year-old, 7-foot (2.13-meter) former basketball star, was not in the building at the time, while the two women working in the third-floor office on 18 Moutsopoulou Street in Pasalimani were unharmed. The blast caused minor damage to the office door, as well as to a flat on the same floor. A group called «Popular Resistance» said it had carried out the attack but did not explain why. Fassoulas, a member of Greece’s European Championship-winning national team in 1987, expressed amazement. «I never expected to be a target, being an MP,» he said. PASOK and opposition parties condemned the attack. Popular Resistance debuted on June 5 with a bomb attack on the Interamerican offices in Alimos, southern Athens. Nobody was hurt, and the blast caused little damage.
