Morocco's state news agency says transport authorities have closed Casablanca airport and four others because of a cloud of volcanic ash from Iceland. The "MAP" news agency cites the Transport Ministry as saying the airports are closed until Tuesday afternoon «to guarantee a maximum level of security for passengers.» The airports affected are Casablanca, Rabat-Sale, Tangiers, Tetouan and Essaouira. Morocco's airports were not affected when the eruption of the volcano in Iceland forced a five-day suspension of air traffic in Europe last month, according to a report of the Associated Press.
