Three people were found shot dead Tuesday in a car dumped in a ditch on the French Mediterranean island of Corsica, a source close to the inquiry into their killings said.
The bodies were found in a mountain village near the town of Corte in the north of the island, which has suffered three decades of low-level violence by separatists opposed to French rule.
The victims, who the source said had probably been ambushed, were found by a driver who had spotted the car in the ditch.
The three victims, who are Corsican but whose identities have not been confirmed, were known to the police, the source said.
A dozen men have been shot dead in Corsica since the start of the year. Police say many of them were victims of score-settling in ongoing feuds among organised crime gangs.
The latest deaths come less than a week after a British-Iraqi family was gunned down in the French Alps. The bullet-ridden bodies of three of the four dead were fond in a car in an isolated forest road.
On Monday, a series of explosions rocked seven supermarkets in Corsica, claiming no victims and causing only minor damage, police said.
The blasts hit supermarkets in the island's main city Ajaccio and in the Upper Corsica region. There was no immediate claim of responsibility.
The holiday island, with a population of 306,000, has more supermarkets per head than any other region of France and plans for a new hypermarket in the suburbs of Ajaccio were abandoned last year after many complaints.
In recent years there have been numerous bombings by the Corsican National Liberation Front but they have mainly targeted holiday homes of people from the mainland.
