UPDATE 1-Iceland volcano erupts again, no flight disruptions

A volcano in Iceland erupted for the fourth time since December on Saturday, the country's meteorological office said, spewing bright orange lava into the air. Livestreams from the area showed fountains of molten rock soaring from fissures in the ground after authorities had warned for weeks that an eruption was imminent on the Reykjanes peninsula just south of Iceland's capital Reykjavik. "Warning: An eruption began in Reykjanes," the Icelandic Meteorological Office said on its website, while Reykjavik's nearby Keflavik Airport's website showed it remained open both for departures and arrivals.
