(CNN) -- An explosion in western Paris early Wednesday shattered several windows of the Indonesian Embassy, the Indonesian Ministry of Foreign Affairs said.
No casualties were reported from the blast, which damaged other buildings nearby, the ministry said in a statement.
Police are investigating the explosion, which took place around 5:15 a.m. Paris time in the upscale 16th district of the French capital. The precise target of the blast is unknown at the moment, the statement said.
The "tremendous explosion" appeared to have come from two cars parked in the street, according to Sid Hagan, a former U.S. soldier who lives in Paris and says he witnessed the explosion.
The area around the explosion was cordoned off, Hagan said.
The scene of the blast is a few hundred meters from the Trocadero gardens, a popular spot where tourists gather to enjoy views of the Eiffel Tower.
