French air traffic controllers strike against EU plans

12 June 2013 Last updated at 11:06 BST

Half of flights serving France's big cities have been cancelled, as air-traffic controllers begin a three-day strike to protest against EU plans to create a single European airspace.

The controllers say the Single European Sky (SES) project will affect public safety and their working conditions.

Walk-outs are expected to spread across Europe on Wednesday.

Francois Ballestero, political secretary for civil aviation at the European Transport Workers' Federation explained why the strike is taking place.
