Extensive disruptions have hit Belgian air traffic this week after drones were spotted near the airports in Brussels and Liège. There were also reports last weekend of unidentified drones, including near a military base.
Following a request from Belgium, Britain is assisting the country with personnel and equipment from the Royal Air Force, Defence Secretary Richard Knighton told the BBC .
Belgium is also reported to have received promises of support from Germany and France.
The incidents follow a series of similar drone violations of airspace in various NATO countries in Europe recently.
