A residential building in Monaco is hit by an explosion on Monday evening, leaving three people wounded, according to multiple reports. French media say the blast happens at around 9 p.m. (1900 GMT) on a street near the French border. Monaco’s head of government, in comments carried by AFP, describes the incident as “very likely an attack,” and authorities are treating it as a deliberate act. The search then shifts to tracing a suspect, with reports describing a police hunt following CCTV footage. The Guardian reports that CCTV shows a man dropping a backpack in the lobby area of the building before the blast, and that two of the injured people are in critical condition. Other outlets describe the device as a makeshift bomb, though details remain under investigation. One report also claims that an injured person may be a Ukrainian oligarch, citing a source close to the investigation; that information is not confirmed across the other summaries. Across coverage, authorities continue to investigate the circumstances of the explosion and the identity and whereabouts of the person suspected of involvement.
