The European Parliament “calls on Member States to immediately lift restrictions on the use of Western weapons systems delivered to Ukraine against legitimate military targets on Russian territory,” said the non-binding resolution.

The motion added that such restrictions weaken Ukraine's ability to defend itself, leaving its population and infrastructure exposed to attacks, Politico reported.

With Ukraine’s ability to launch long-range missiles into Russia hindered, Kyiv has opted to use drones to hit targets.

Russia ramps up drone production

Drones have also been extensively used by Russian forces. Putin on Thursday announced a tenfold increase in the production of such machines.

"In total, about 140,000 unmanned aerial vehicles of various types were delivered to the armed forces in 2023," Putin said. "This year, the production of drones is planned to increase significantly. Well, to be more precise, almost 10 times.

"Whoever reacts faster to these demands on the battlefield wins," Putin added at a meeting in St. Petersburg about developing drone production.

Since Russia sent tens of thousands of soldiers into Ukraine in February 2022, the war has largely been a story of grinding artillery and drone strikes along a heavily fortified 1,000-km front.
