According to the French Interior Ministry, one person was killed on Thursday and another one was injured as a parcel bomb exploded in center of Paris.

The explosion occurred in a building on Boulevard des Malesherbes, in the eighth district, near the Champs-Elysees, in a law office.

It is believed that the victim is a female secretary who opened the parcel, CNN reports.

Lawyer Christian Charriere-Bournazel said: "Someone came to the office and left a package. The secretary that opened it in fact opened a parcel bomb. The parcel bomb killed her."

According to AFP, five other people were injured in the blast.

The building has more law offices. Among them there is the law firm co-founded by French President Nicolas Sarkozy in 1987 where he worked as a lawyer and which bore his name until May 9 of this year, when he became president. Still, no immediate link was made.

It wasn’t clarified what was the target of the blast.

In the same building there is an office for a foundation in the memory of the Holocaust.

According to Serge Klarsfeld, a former Nazi war criminal hunter connected with the Holocaust information, said that he didn’t think that the office was the target.

Police sealed the scene and remained around. It also blocked the boulevard.

A second explosive device was found and deactivated by police shortly arriving at the scene of the accident.

French Interior Minister Michele Alliot-Marie abruptly ended her trip to Brussels and is expected to arrive at the site.

She said in a statement that she “condemns with the greatest severity this cowardly and hateful act.”
