A bomb hidden in a package exploded outside an apartment building in Monaco on June 29, 2026, injuring a wealthy Ukrainian businessman named Vadym Iermolaiev, along with his wife and child. The blast happened around 9pm local time. Police are now searching for the person who sent the package and fled the country.

Iermolaiev is the owner of Alef, a large company based in Ukraine that buys and sells industrial goods. His name makes him a possible target from different directions. Ukraine's government had previously punished him for allegedly doing business in Crimea, the region Russia seized in 2014 and occupied after 2022. This put him in a tricky spot: he is not a friend of the Ukrainian government, yet nothing in public records suggests he works for Russia either.

The use of a bomb hidden in a package matches attack methods used in Europe since Russia invaded Ukraine in February 2022. This pattern has targeted Ukrainian business leaders and officials living abroad. Monaco—a tiny country about the size of a large neighborhood—is a place where wealthy people often live. It is also small enough that someone fleeing after an attack would have limited options for escape.

All three victims were hurt seriously. Doctors have not publicly said how badly each person was injured.

Police have not named a suspect or explained why the bomb was sent. Investigators will focus on examining the device, looking at security camera footage from the building's entrance, and working with French police. Monaco has close ties to France in matters of law and security. Whether this was a professional killing operation or something hastily put together will change how police investigate and what happens next.
