Officials in Monaco have stated that, at this point, they do not believe “terrorism” was the motive behind an explosion that injured three people.

The powerful detonation occurred Monday evening at the entrance of a residential building, shortly after a man reportedly left a package at the scene.

Prosecutor Stephane Thibault told journalists on Tuesday that the suspect, who escaped on foot, appears to have acted alone and has not yet been apprehended.

Footage from security cameras shows the individual walking along a nearby street dressed in a black jacket, light-colored trousers, white shoes, and a black hat partially obscuring his face.

Authorities have launched an investigation for attempted murder but are not treating the case as an act of terrorism, Thibault said, noting that the motive is still unknown.

‘Caught in the explosion’

Among the three injured, a woman remains in critical condition. Her partner and a 13-year-old child sustained less serious injuries but are still receiving hospital care. Thibault did not release their names.

Several media outlets reported that Ukrainian construction magnate Vadym Yermolaiev was among those hurt. According to Ukrainian sources, he was placed under Ukrainian sanctions in 2023 over alleged connections to Russia.

The victims were “apparently returning home calmly” in the early evening, based on surveillance footage, Monaco’s minister of state, Christophe Mirmand, told a French television broadcaster.

“They were struck by the blast as they stepped into the entrance of their apartment building,” he said.

Ukraine’s Foreign Ministry confirmed it is in contact with authorities in Monaco, stating that the three injured individuals are members of a family of Ukrainian origin. Their identities have not been disclosed, and officials are working to verify their citizenship status.

Yermolaiev, a wealthy resident of Monaco, has been under Ukrainian sanctions since December 2023. Reports indicate the measures were linked to his business activities in the alcohol sector in Russian-occupied Crimea.

Monaco, a small principality with a population of about 38,000, is home to many affluent residents. It is widely regarded as one of the safest countries in the world, supported by an extensive network of surveillance cameras monitoring most public areas.
