A letter has exploded at the International Monetary Fund (IMF) office in Paris, injuring the employee who opened it, police say.
The IMF employee was injured in the hands and face, and staff evacuated.
In another development, German finance ministry in Berlin intercepted a parcel bomb sent to Finance Minister Wolfgang Schaeuble on Wednesday.
A Greek far left group, the Conspiracy of Fire Cells, said on a website that it had sent the device.
The IMF is one of three organisations, along with the European Commission and the European Central Bank (ECB), which bailed out the Greek government after it came close to defaulting on its debts.
