The ash cloud from the erupting Icelandic volcano is causing further disruption to air travel as it sweeps over Europe. More than 200 delays and cancellations have been reported in parts of Scandinavia, Ireland and Scotland, while a threat hangs over services in England. It follows Saturday's eruption of Iceland's most active volcano - the largest in 100 years. The ash in the atmosphere affects visibility and can clog engines, making it too dangerous to fly. Fears remain there'll be a repeat of last year's travel chaos - when a different Icelandic eruption closed much of Europe's airspace for a time.
