Sweden's airspace will shut by 2000 GMT Thursday due to the ash cloud created by a volcano eruption in Iceland, the country's civil aviation authority said. 'We are closing airspace sectors one by one and we are following the ash cloud ... Its coming from the northwest' of Sweden, LFV aviation authority spokesman Carl Felling told selfnews. The entire airspace would be shut by 2000 GMT. 'We will close Malmoe and the south parts of Sweden at 1400 GMT, and everything except the Baltic Sea and the island of Gotland will close by 1600 GMT,' he said.
