Explosive experts in Thessaloniki, northern Greece, were yesterday examining the remains of three gas canister bombs that went off in different parts of the city in the early hours. The first makeshift device was placed under a van belonging to OTE telecom parked on Constantinou Karamanli Street and went off shortly after 4 a.m. The explosion damaged the vehicle but none of the adjacent properties. The second blast was almost simultaneous and took place at the entrance of a building housing the Thessaloniki Municipality’s Architecture Center, while the third came some 20 minutes later. The third device had also been placed in the entrance of a building, this one housing a branch of a local technical college on Megalou Alexandrou Street. Firefighters extinguished the blazes at all three blast sites, containing the damage. No injuries were reported.
