A booby-trapped envelope blew up at the home of an appeals court judge in the Greek capital Sunday evening. There were no injuries, media reports said Monday.
The explosive device was hidden in a small package which exploded shortly after delivery.
The recipient judge has presided over several trials in terrorism related cases, Xinhua quoted police as saying. No one claimed responsibility for the attack.
Police suspect local guerrilla groups which have plotted similar attacks against politicians, police, and judicial and business targets.
