British-made drones will be used to build a "drone wall" to protect Nato from Vladimir Putin's Russian aggression.

The low-cost unmanned craft will be developed in collaboration with Ukraine and is part of a new strategy to deter Mr Putin's jets and drones on Nato's eastern flank.

European ministers have raised concerns about Russia breaching the airspace of both Poland and Estonia, which prompted the UK to deploy RAF Typhoons over Poland.

A suspected Russian "hybrid" incursion of drones also unfolded this week in Denmark and Norway.

Defence Secretary John Healey told The Telegraph that the "reckless" and "dangerous" manoeuvres by Moscow would be answered back by Nato countries, including new border defences.

Codenamed Project Octopus, the UK has launched a drone-building programme with Ukraine, which will see interceptor drones built in British factories within weeks and deployed to prevent Russian aggression.

European ministers met on Friday to discuss the "drone wall" concept, which would involve stationing ground-launched drones on the border to tackle Russian drones or missiles.

Over the weekend, Russia launched over 500 drones and 40 missiles into Ukraine, killing at least four people.

The UK plans to produce 'thousands' of drones 'to help Ukraine defend themselves'
