PARIS (AP) - Some planes are flying after five days of being grounded by the drifting volcanic ash from an eruption in Iceland, but British officials say London airports will likely remain closed another day.
A statement from the British National Air Traffic Service early today says the eruption "has strengthened and a new ash cloud is spreading" toward Britain.
London is a a major hub for thousands of daily flights worldwide and the drifting volcanic ash has crippled European air travel.
The Eurocontrol air traffic agency in Brussels says it expects some 55 to 60 percent of flights over Europe to go ahead today.
An international pilots group warned that ash remains a danger and safety, not economics should be the main driving factor.
