The Netherlands will supply F-16s to Ukraine, but it's unclear how many would be available and when. Meanwhile, Russia reported drone attacks in three regions.
Ukrainian President Volodymyr Zelenskyy met Dutch Prime Minister Mark Rutte in the Netherlands after the US had approved the transfer of Dutch and Danish F-16 fighter jets for Ukraine's air force.
Both Denmark and the Netherlands confirmed on Sunday that the transfer of planes would take place when the conditions were right.
The confirmation comes as Ukrainian pilots start training to operate F-16 fighter jets, with the process likely to take at least six months, according to Ukrainian Defense Minister Oleksiy Danilov.
Meanwhile in Russia, five people were wounded when a drone hit a train station in Kursk, the regional governor said. It was one of three drone attacks reported in Russia on Sunday.
