Farmers and rescue workers collect sheep near the village of Kirkjubaejarklaustur in the south of Iceland May 24, 2011. People living next to the glacier where the Grimsvotn volcano burst into life on Saturday were most affected, with ash shutting out the daylight and smothering buildings and vehicles. An ash cloud from a volcano on Iceland shut down flights in northern Britain and elsewhere in north Europe on Tuesday and was heading to Germany, but officials expected no repeat of last year's air chaos.
