Heavy fog caused disruptions across Western Europe, with low visibility leading to significant flight delays on Monday. There were delays at airports in London, Paris, Amsterdam, Frankfurt, Berlin, and Brussels, where visibility reportedly dropped to just 100m. The situation was worsened at Dusseldorf Airport by the discovery overnight of an unexploded World War Two bomb. A controlled explosion closed the airport to flights for an hour. According to Eurocontrol, the European air safety agency, there were more than 120,000 minutes of flight delays across the continent on Monday morning, with 94% due to adverse weather conditions. Several airlines warned that delays were expected to continue throughout Monday. There were widespread delays at UK airports. Heathrow airport said it expected to cancel around 10% of flights on Monday, while London City was forced to close to all traffic. Other affected airports include Manchester, Leeds Bradford, Glasgow, Belfast and Cardiff.
