The device detonated as residents were entering the building. French broadcaster BFMTV reported that among the injured are Yermolaiev, his wife, and their 13-year-old son. The businessman and his wife were hospitalized in serious condition, while Monaco prosecutors said the teenager’s life is not in danger. Monaco government chief Christophe Mirmand said authorities are treating the incident as a possible terrorist attack, calling it “the first such case in the history of the principality.” Preliminary findings suggest the explosive device was packed with bolts and metal pellets to maximize damage. Police are currently searching for the suspect who left the backpack at the scene. Yermolaiev is the founder of the Dnipro-based industrial and trading group Alef and a long-time figure on Forbes’ list of Ukraine’s wealthiest individuals. His fortune was estimated at $220 million in 2021.
