PARIS (AP) _ McDonald's took out full page advertisements in French newspapers on Saturday, calling for an end to attacks against its restaurants after a 28-year-old employee was killed in a bomb blast in northwestern France.

The advertisement, headlined ``Enough,'' appeared on the day Laurence Turbec was buried in her home town of Trelivan, in the Brittany region. She was killed last Wednesday when a bomb ripped through a McDonald's restaurant near the city of Dinan.

Authorities suspect the bomb that killed Turbec was planted by the Breton Revolutionary Army, a separatist movement seeking autonomy for the western region, which has maintained a strong cultural identity reflecting the Bretons' Celtic origins.

Also early on Saturday, an incendiary device caused slight damage to a McDonald's outlet in the southwestern Pyrenees-Atlantiques region, but no one was hurt, firefighters said.

The device caused a fire, which damaged chairs, tables and a childrens' play area outside the restaurant. Police said there was no evidence linking the attack to the bombing in Brittany.

Saturday's advertisement expressed sympathy for Turbec's family. It was signed by the head of McDonald's France, Denis Hennequin, and the head of franchises, Patrice Ruspini.

``McDonald's is men, women, children, parents, people who work, people who love life. It is not just a symbol. By targeting McDonald's the worst has happened. That's enough,'' the advertisement read.

Authorities have opened a judicial inquiry into the McDonald's attack as well as into a bombing attempt in the nearby city of Rennes, also last Wednesday. Police defused the Rennes bomb, which was placed in front of a downtown post office.

Investigators believe the two incidents were linked. Explosives found at both scenes are thought to be part of a large stock of dynamite stolen in September from a company in the Breton town of Plevin.

After the theft, police recovered more than half the dynamite and arrested eight Breton and five Basque separatists. Then, in March, the Breton Revolutionary Army claimed responsibility for an attack that made use of some of the explosives that weren't recovered.
