EU eyes building ‘drone wall’ against Russia – but what is it?

European Union leaders are discussing setting up a “drone wall” of defences after high-profile air incursions by Russia.

But the plan appears to mean different things to different countries, and not everyone seems entirely convinced.

The first call for the project came last month from EU chief Ursula von der Leyen in the hours after a swarm of Russian drones breached Poland’s airspace.

While details were scant, the initial plan appeared clearly focused on helping to shore up the EU’s eastern frontier from the threat from Moscow.
