Russia and Ukraine have traded air strikes, after a week of intensifying rhetoric in which Russia tested a new missile on Ukraine. Russia has made close to 1,500 strikes on Ukraine since Sunday evening on about half of the country's regions causing dozens of injuries, Ukrainian President Volodymyr Zelensky said.

Tit-for-tat moves this week included the use of American-made ballistic missiles to strike inside Russia, and new nuclear threats from Moscow. Neither appear to have influenced the war on the ground.
