Three people were found shot dead Tuesday in a car on the French Mediterranean island of Corsica, a source close to the inquiry into their killings said.
The bodies were found in a 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.
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.
The latest deaths come less than a week after a British-Iraqi family was gunned down in the French Alps.
Saad al-Hilli, his wife Iqbal and her mother were found dead in their car in a forest car park near the village of Chevaline on September 5. A passing French cyclist was also killed.
The Hillis's daughter Zainab, aged seven, was seriously wounded and her four-year-old sister Zeena escaped by hiding under her dead mother's skirts.
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.
