Thousands of people have taken to the streets of Corsica to protest at what they say is French government repression. The demonstration follows a recent wave of arrests of people linked to France's most wanted man Yvan Colonna, who is accused of murdering Corsica's governor Claude Erignac in 1998. Erignac was killed by Corsican separatists who ended a truce with the French government three days ago. Overnight at least eleven people were injured in two explosions at the treasury building in Nice, southern France. There's suspicion but no confirmation that Corsican extremists are behind the blast. Armed separatists have waged a bitter 30-year war for independence from France. 30 percent of Corsicans back their goal, if not the means to achieve it. Colonna was arrested two weeks ago and has been sent to Paris to face trial for murder. He is believed to be behind the killing of Erignac, who was shot three times in the head in front of his wife. **PHOTO CAPTION*** French Interior Ministry photo of Yvan Colonna.
