Fire cuts power to 45,000 in French Riviera, sabotage suspected

{}French Riviera authorities said Sunday they are boosting security around electricity grid sites after an overnight fire in a substation that cut power to 45,000 people, and a massive blackout during the Cannes film festival blamed on sabotage. On Saturday, a five-hour power cut disrupted the final day of the Cannes festival, knocking out traffic lights and ATMs and forcing organisers to use back-up generators.
