Ukrainian authorities are growing frustrated with a surge in foreign components being found in Russian drones, with a senior diplomat calling on allies to tighten sanctions controls as Moscow scales up military production.

Vladyslav Vlasiuk, Ukrainian President Volodymyr Zelenskyy¡¯s special envoy on sanctions, said the European Union¡¯s sanctions regime is showing cracks as enforcement is carried out by member states rather than the bloc as a whole ¡ª even as the Kremlin expands large-scale aerial attacks.

¡°We would like the European Union to step up exports control for European companies,¡± Vlasiuk said in an interview in Kyiv.
