The first shipment of Leopard 2 tanks from Germany has been sent to Ukraine, the German defence ministry says.
Eighteen cutting-edge main battle tanks were delivered after Ukrainian crews were trained to use them.
Defence Minister Boris Pistorius said he was sure the tanks could “make a decisive contribution” on the frontlines of the war.
Challenger 2 tanks from the UK have also arrived, according to reports from Ukraine.
Ukraine has been calling for more modern vehicles and weapon systems for months to help fight Russia’s invasion.
