Police say arsonists have attacked the home of the brother of government spokesman Simos Kedikoglou with a firebomb.

The arsonists broke down the door with a sledgehammer and threw a firebomb inside, police say.

Police say the occupants of the house - the spokesman's brother, his wife and their 3-year-old child- were unharmed. They added that the occupants had extinguished the fire.

Arsonists attacked the homes of five prominent journalists before dawn Friday, prompting the government spokesman, a former journalist, to condemn the attacks. Two small anarchist groups claimed responsibility for those attacks, which caused limited damage and no injuries.
