At least three people were injured in what authorities described as an intentional “attack”
At least three people were injured after a backpack bomb exploded outside a residential building in Monaco on Monday evening. A manhunt was launched after the blast, with the suspect still at large.
The blast occurred shortly before 9pm on Rue Révérend Père Louis Frolla, a street in the principality near the French border.
A suspect was allegedly caught on CCTV leaving a backpack near the entrance to the building just as several people were entering, before fleeing on foot toward Beausoleil, a French commune bordering Monaco.
At least three people were injured, two of them seriously, while a third sustained minor injuries. Police sources cited by BFMTV said the victims were of “Ukrainian and Russian origin.”
Meanwhile, Le Figaro claimed that the victims were all members of the same family, one of whom is “potentially a Ukrainian oligarch.” The parents, aged between 50 and 60, are reportedly in critical condition, while their 13-year-old son is in stable condition.

Monaco authorities also activated the “red plan,” an emergency response protocol used in the event of a sudden incident causing multiple casualties.
Eric Ciotti, the mayor of neighboring Nice, described the incident as an “attack.”
“The attack carried out this evening is a tragedy that strikes Monaco,” Ciotti wrote in a post on X. “Thoughts for the victims, their families, and the people of Monaco. Total support for the security forces and emergency services mobilized.”
Monaco’s Minister of State Christophe Mirmand told AFP that the explosive device likely contained bolts and shot, adding that police were still gathering evidence. He indicated that investigators were treating the blast as a likely terrorist attack, according to local media.
