A bomb exploded at a real-estate agency Thursday and another explosive was defused at a sports rehabilitation center in French Basque country, police said. No injuries were reported.
The bomb went off hours before dawn, damaging the real-estate agency's office in Anglet, a town in southwest France, local police said. The phrase "Basque country is not for sale" was spray-painted across the building facade.
The same phrase had been sprayed on other real-estate agencies' offices in the region during a wave of bombings last year.
Anglet Mayor Jean Espilondo called the bombing "unacceptable."
There was no immediate claim of responsibility, a judicial official said in Paris. The armed Basque separatist group ETA has waged a sometimes violent campaign for an independent Basque homeland in northern Spain and southwest France since the 1960s.
