Letter bomb explodes at IMF's Paris office

A letter bomb has exploded at the International Monetary Fund's offices in Paris, causing injuries to one worker.

The building near the Arc de Triomphe monument was "as a precaution", a police source told AFP.

Police told Reuters that the letter bomb caused "slight injuries" to the worker.

The secretary who opened the letter was injured by shrapnel in the face and hurt in the eardrum because of a "rather violent noise", the police chief said.

Although no link has been established, suspicion has fallen on far-left organisations.

On Thursday a Greek far-left group claimed it had sent a parcel bomb to the German finance ministry in Berlin more than six years after waging a similar campaign against European officials.

"We claim responsibility for sending a booby-trapped parcel to the German finance minister," the Conspiracy of Fire Nuclei group said in a statement posted on an anti-establishment website.

German police said it had found an "explosive" package at Finance Minister Wolfgang Schaeuble's office on Wednesday.
