With the war between Russia and Ukraine now well into its fourth year, Moscow has turned to a new jet-powered attack drone in a bid to gain a quick advantage.
Just as Kyiv believed its drone-killing interceptors would be their greatest new weapon, Russia has gone to China for help in getting the latest upper hand.
Last week, talks between Russian President Vladimir Putin and his Chinese counterpart Xi Jinping in Beijing were partly focused on the war in Ukraine.
A new Russian attack drone can reach speeds of up to 310mph thanks to its turbojet engine, Ukrainian intelligence says.
