Greek police arrest three over car blast killing politician's mother

Greek anti-terror police arrested three individuals in Thessaloniki and Crete for a July 1 attack targeting ruling New Democracy party politicians. Homemade gas canister explosives were used against homes and vehicles of three party figures. The mother of former candidate Afroditi Nestora died from injuries sustained in a car explosion while trying to extinguish a fire. Nestora, her father, and two others were also injured. Separately, two more people were detained in connection with a 2010 firebomb attack that killed three. Leftist and anarchist groups in Greece frequently use improvised explosives against political targets, banks, and companies.
