MONACO — An explosion struck a residential building on Rue Révérend‑Père‑Louis‑Frolla shortly before 9 p.m. on Monday, June 29, 2026, injuring three people. Two of the injured were in critical condition, and among them was a Ukrainian oligarch or tycoon. The blast was caused by a makeshift parcel bomb placed in a backpack, according to surveillance video that captured a man dropping the backpack before the detonation.

Police identified a male suspect who fled on foot, possibly toward France. Monaco police are cooperating with French police in the investigation, and both forces are searching for the suspect.

Accounts differ over the nature of the incident. Monaco authorities described the blast as a very likely attack or a deliberate act, while other statements from the same authorities said the explosion was not a terrorist attack. Additionally, reports conflict on the gender of a 13‑year‑old victim: some sources identified a 13‑year‑old girl, while others reported a 13‑year‑old boy.

A separate report noted that two adult victims, aged between 50 and 60, were also injured. The statement that the explosion was not a terrorist attack was reported by TASS. The gender-specific reports were attributed to Kyivindependent (girl) and TimesNowNews.com (boy).
