Dutch airspace is to remain closed until further notice, air safety inspectors said on Friday morning, as the cloud of volcanic ash from Iceland moved southwards across Europe.

KLM had already announced there would be no flights until 14.00 hours at least, while Transavia had cancelled all flights until 18.00 hours.
Flights across much of Europe have been cancelled in the second day of disruption since the volcano erupted. Hundreds of thousands of passengers have been affected and officials told the BBC the disruption could extend until after the weekend.

According to the KNMI weather bureau, the ash cloud is travelling at some 40km per hour but said it would be later on Friday morning before experts could say that the risk to airline traffic is over.
‘You don’t know what is coming along next,’ he said.
The tiny particles of rock, glass and sand in the ash have caused aircraft motors to jam in the past.
By 8.00 hours Amsterdam’s Schiphol airport is largely deserted apart from a few passengers whose flights were cancelled on Thursday and rebooked to travel on Friday, news agency ANP reports.
Some 2,000 people spent the night at the airport on camp beds in the customs area.
But there are long queues at the airport’s railway station as holidaymakers try to buy tickets to get home by train, ANP said.
