A number of flights between Ireland and the UK have been called off this morning as a result of bad weather conditions.

The blanket of heavy fog over parts of Ireland and the UK has yet to lift after three days, meaning many passengers were left stranded at Dublin Airport this morning.

Three flights out of Dublin so far have been cancelled, at 6.35am, 7.50am and 8.45am. Passengers at Shannon and Belfast Airports have also been delayed by several hours, while four flights from London to Dublin have been pulled.

Yesterday over 100 flights out of Heathrow were cancelled due to the adverse conditions.

Thankfully Met Éireann says the fog should lift during the morning, while UK's Met Office has lifted its "be aware" warning.

Aer Lingus and other airlines have promised that passengers on cancelled flights will be re-accommodated or entitled to a refund.

The flight problems have affected a number of international passengers travelling to Dublin for the Web Summit this week, which will see 40,000 attendees descend on the capital for the massive tech conference.

Web Summit founder Paddy Cosgrave took to Twitter this morning to sympathise with those experiencing travel issues,

To our many attendees & speakers caught in fog around Europe, we hope today is better. Safe travels.
