A woman was killed early Saturday in the northern Greek city of Thessaloniki when a bomb she was carrying exploded in her hands, police said.

The 38-year-old woman apparently was carrying the bomb to place outside a nearby bank around 5 a.m., police said.

Several storefronts and vehicles were damaged by the explosion.

Police said the woman, whom they did not publicly identify, had a criminal record related to drugs and prostitution and had been involved in at least one robbery and thefts in the past. The Greek police’s division for organized crime was investigating the incident, while authorities were also investigating whether the woman might have had ties to extreme leftist groups.
