A suspect has been identified in the investigation into a parcel bombing in Monaco that seriously wounded a sanctioned Ukrainian multi-millionaire and two others.

Monaco's prosecutor's office says an arrest warrant has been issued for the suspect, who they say is a foreign national and no longer in Monaco. An Interpol red notice was also being issued, they added.

A package left in the entrance of an apartment building on Monday evening exploded shortly afterwards.

No details have been given about the suspect. CCTV cameras pictured a figure in a dark bucket hat and French media report it was a Ukrainian woman in her 30s.

Monaco's public prosecutor, Stéphane Thibault, made no comment on the French reports, but was expected to give further details later on Friday.

After the explosion at an apartment building near Monaco's border with France, a suspect was seen fleeing towards the French commune of Beausoleil. Authorities in the principality have said the incident is being investigated as attempted murder, not as a terrorist attack.

The prosecutor thanked police from Monaco and France for their co-operation which made it possible "to identify, in a particularly short time, the person suspected of having carried out the attack."

"An arrest warrant has been issued for the suspect, who will be the subject of an Interpol Red Notice from this evening," the Monaco prosecutor's office said on Thursday night.

The three victims, who included a 13-year-old, have been treated in hospital and the two adults were initially said to be in a critical condition.

The victims' identities have not been confirmed by Monaco authorities, but according to local reports, the attack targeted Vadym Yermolaiev, his partner and his son.

On Wednesday, the man was no longer in a life-or-death situation, but the woman's condition had not yet stabilised, AFP reports. The 13-year-old suffered minor injuries.

Yermolaiev, 58, is a wealthy real estate developer, who has been living in Monaco. He is a Cypriot citizen after renouncing his Ukrainian citizenship in 2019.

He has big interests in the wine and alcohol business in Russian-annexed Crimea, and since 2023 has been the subject of sanctions imposed by the government in Kyiv.

He was named the 39th richest Ukrainian by Forbes magazine in 2020, with a fortune of $230m (£173.8m).

Monaco's Prince Albert II described the incident as a "heinous crime".
