In Monaco, a powerful explosion in a residential building injured Ukrainian oligarch Vadim Yermolaev and two other people, AFP reported on the night of Tuesday, June 30. According to the authorities in Monaco, as a result of the explosion of a bomb-laden bag, which occurred on the evening of June 29 near Place de Moulins in Monte Carlo, two adults sustained life-threatening injuries, while a 13-year-old teenager suffered minor injuries. All three injured individuals were taken to hospitals in French Nice, located 20 kilometers from the scene of the incident, on Rue du Père Louis Frolla, which runs along the border with France. An informed source at the investigative authorities confirmed to AFP that one of the injured is Ukrainian businessman Yermolaev, who resides in Monaco. This was also reported by several Ukrainian media outlets citing their own sources. **The First Such Incident in the Principality** According to local authorities, surveillance cameras recorded that before the explosion, the suspect left a bag or box containing an explosive device, likely filled with bolts and pellets, in the lobby of the residential building and then fled on foot towards France. Exits from Monaco have been blocked. The cause of the explosion and the background of the incident are being investigated. The Minister of State (head of government) of the principality, Christophe Miéville, initially stated that it was likely a terrorist act, but later changed his wording to "intentional explosion." According to him, this is the first such case in the history of the principality. Around fifty firefighters and more than 80 security personnel were involved in assisting the victims and securing the explosion site. In 2021, Forbes Ukraine included businessman and investor Vadim Yermolaev in the list of the 100 richest Ukrainians, estimating his wealth at $220 million. In 2019, he renounced his Ukrainian citizenship and obtained citizenship of Cyprus. In 2023, Kyiv imposed personal sanctions against Yermolaev, according to "Deutsche Welle."
