The government said cooking gas canisters were used to set fire to two political party offices and the homes of a conservative politician and a professor on Tuesday morning. No one was injured.

A previously unknown group calling itself Post-Midnight Slalom said it set the fires Tuesday to protest corporate influence on next summer's Olympics and the arrest in June of seven rioters during the European Union summit in Thessaloniki.

One of the propane tanks burned the home of Giorgos Voulgarakis, a conservative lawmaker. He was not home; firefighters rescued his wife and four children. Several cars were also damaged by the fires.
