Angry residents in San Juan line up for food and gas as a major power outage plunges much of Puerto Rico into darkness. "The truth is that we have been dealing with this problem for a while," Ismael Perez, a resident of Dorado, tells AFP. "The companies that were there before worked much better than what we have now, unfortunately," Perez adds. The US island territory's electric utility says restoration could take up to two days. The "island-wide blackout" began at 5:30 am (0930 GMT), Luma Energy, which manages power transmission on the island, said in a social media statement. IMAGES AND SOUNDBITES
