Bomb disposal experts defused a letter bomb received by the Greek Embassy in Paris Monday.

Embassy staff called the police when the letter from Italy, addressed to the ambassador with no return address, emitted smoke from a basement storage room. The police detected wires and a battery inside the enveloped and doused it with water preventing an explosion.

It was the third letter bomb detected in Europe in the last week.

On Thursday, a letter bomb received by the Deutsche Bank office in Frankfurt and intended for its CEO Josef Ackermann was discovered through a mail room X-ray but failed to detonate. The Italian anarchist group Federazione Anarchica Informale (Informal Anarchist Federation) claimed responsibility for sending the letter bomb.

German authorities are looking another letter bomb as a note found in the Deutsche Bank letter bomb mentioned "three explosions against banks, bankers, ticks and bloodsuckers," according to AFP.

Another letter bomb received by Italy's tax collection office in the outskirts of Rome on Friday exploded when the director, Marco Cuccagna, opened it. Cuccagna was injured in the face and hand by pieces of glass from a desktop that shattered during the explosion.

No one has claimed responsibility for the attack but police suspect that the FAI is also responsible.
