A letter bomb exploded at the Paris offices of the International Monetary Fund on Thursday, injuring a secretary who suffered burns to her hands and face, police said.
Employees were evacuated from the building near the Arc de Triomphe monument in the heart of the capital “as a precaution” after the late morning explosion, a police source said.
IMF chief Christine Lagarde condemned it as a “cowardly act of violence”.
She reaffirmed “the IMF’s resolve to continue our work in line with our mandate”, according to a statement issued by her office.
“We are working closely with the French authorities to investigate this incident and ensure the safety of our staff.”
French President Francois Hollande called it an “attack”, saying it showed that “we are still targeted.”
The victim, a secretary for an unnamed senior manager, suffered light burns from the blast which might have been caused by a firework, a police source told AFP, asking not to be named.
Armed police and soldiers were seen securing the area around the IMF offices.
