In a shocking incident that has rattled Monaco and stretched into southern France, a parcel bomb detonated in a residential building on Rue Révérend Père Louis Frolla near the border, seriously injuring Ukrainian real‑estate magnate Vadym Yermolaiev, his wife, and their 13‑year‑old son.

The wounded trio were taken to a hospital in Nice, where Yermolaiev and his partner remain in critical condition, according to French media.

Monaco authorities confirmed the explosion was triggered by a parcel bomb, while video footage shows a man dropping a backpack into the lobby shortly before the detonation.

Surveillance also caught the suspect fleeing on foot toward Beausoleil, prompting a major police hunt across the French‑Monaco border; local police and emergency services responded within minutes.

Monaco's Prince Albert II, Minister of State Christophe Mirmand and French officials have condemned the attack as a heinous crime, urging cooperation with French authorities.

Yermolaiev, once a Ukrainian citizen from Dnipro and a known real‑estate developer with interests in Crimea's wine sector, renounced his Ukrainian citizenship in 2019 to become a Cypriot citizen; he has been the target of sanctions by Kyiv since 2023.
