France has tapped its strategic fuel reserves to resupply petrol stations that have run dry, the government said on Wednesday, amid strikes by workers at refineries and depots that have stunted production and blocked deliveries. The action has left more than 60 percent of France's refining capacity offline. Government spokesman Olivier Veran acknowledged "tensions" and said roughly one in every 10 service stations nationally was experiencing some shortages, but that in the north, the figure was closer to one in every three.
