Air travellers are facing prolonged delays after a huge cloud of ash
from an Icelandic volcano provoked the most extensive shutdown

Experts warned the fallout from the Eyjafjallajokull volcano in southeast Iceland,
which covered the skies of northern Europe yesterday, could take several days to clear.
