Five people have been killed in overnight strikes in Russia and Ukraine, as the two sides continue to trade drone attacks. Ukrainian officials said on Saturday that more than 200 drones and almost 30 missiles were fired by Russia, with most targeting Dnipropetrovsk where three people died.

The Washington-based Institute for the Study of War noted that cooperation with China has allowed Russia to bypass Western sanctions on imports of electronics for drone production. Ukraine’s military intelligence estimates that Russia receives up to 65% of components for its Geran drones from China. Beijing rejects the claims.
