An explosive device went off Friday near the home of a socialist party member of the Greek parliament, causing some damage to his apartment building but no injuries, police said. The explosion in the parking lot of the apartment block of MP Dimitris Androulakis, 58, damaged the outside of the building, they said. No details on the nature of the device were released. The number of attacks using explosive devices has been rising in Greece since widespread riots in December last year following the death of a youth in a confrontation with police. Last month a bomb targetted the Athens home of conservative politician Marietta Giannakou, but left no injuries. Three days earlier six police officers were injured in an attack on a police post.
