A bomb policeman said her hand exploded and a Greek woman was killed earlier on Saturday.

The 38-year-old woman has not yet been publicly confirmed, apparently carrying a bomb to place it outside a bank in the northern city of Thessaloniki, about 5 a.m. local time. The explosion damaged several stores and vehicles.

"It seems she is carrying an explosive device and plans to plant it as an ATM for the bank," a senior police official told Reuters. "What went wrong, the explosion in her hand."

The woman died of hospital injuries.

Police said the woman had a criminal record related to drugs and prostitution and had at least one robbery and theft in the past. The Greek police's Organized Crime Ministry is investigating the incident, and authorities have also investigated whether the woman may have links to extreme left groups.

An explosion near the train office caused limited damage to the building and no injuries. Anonymous calls were made on local media 40 minutes before the explosion warned the device, causing police to evacuate and evacuate the area.

The group claiming responsibility said bombing was part of the armed struggle with the state.

The bombing of the train office comes after the second anniversary of Greece's worst railway disaster, when freight trains and a passenger train heading in the opposite direction caused the killing and dozens of people were injured.
