Bomb explosion in central Athens kills 1, injuring 1

Greek television channels interrupted their programs with breaking news about the blast which occurred around 11:15 p.m. local time. According to unconfirmed information the body of the dead person is dismembered and his identity is unknown.

Speaking to Greek Press on the condition of anonymity local experts suggest that the dead man could be the person who placed the bomb, which went off earlier than estimated.

According to eye witnesses who spoke to Greek television channels, the dead person is young and could be the 15-year-old son of a poor Afghan woman who was searching for anything useful in the garbage with her family.

Her 10-year-old daughter was slightly injured by the explosion and transferred to a hospital along with the 45-year-old mother who is in a state of shock.

According to local residents, the Afghan family used to go out in the evenings to collect things of little value from garbage.

Police has not confirmed anything officially yet.

An anti-terrorism squad has sealed off the area at Patissia in front of the offices of the Greek Society of Business Management, a state-controlled agency which was most probably the target of the attack, and investigated for clues.

Government buildings, offices of financial organizations, as well as homes of politicians have been frequently targeted by local anarchist guerrilla groups which operate in Greece for decades.

Next to the offices of the Greek Society of Business Management is a cafeteria which was full of people at the time of` the blast.

According to latest information, this time there was no warning telephone call made to local media, as it usually happened when local terrorist groups planned bomb attacks in the past few years.

Terrorist attacks have been stepped up in Greece after the fatal shooting of a teenager by a policeman on December 2008.
