An explosion at the entrance of a residential building in Monaco on Monday evening has left three Ukrainian citizens injured, including a prominent oligarch and members of his family.

Two of the victims are in critical condition, according to initial reports from the scene.

Authorities are treating the incident as a targeted attack, with surveillance footage showing a suspect fleeing the area toward the French border.

The blast, caused by a device concealed in a backpack, has triggered a manhunt involving both Monaco and French law enforcement agencies.

The incident marks a significant escalation in the security risks faced by Ukrainian nationals abroad, particularly those with high public profiles.

While the motive remains unclear, the targeting of a specific family unit suggests a coordinated effort rather than random violence.
