Russian forces have launched a large-scale drone assault across Ukraine, where officials said three people were killed and 64 others wounded.

Since then, Russia and Ukraine have swapped dozens of prisoners of war, focusing on under-25s and the severely wounded and sick. There are hopes they could build into some of the biggest exchanges in the war that was triggered by Russia's 2022 invasion of Ukraine.

Russia launched one of its largest air strikes on Kyiv in over three years of war and struck a maternity ward in the southern city of Odesa, officials said.
