In Russia, at least two people were injured Monday as Russian air defense systems shot down four Ukrainian drones near Moscow. The attacks prompted officials at Moscow’s four main airports to suspend air traffic, canceling dozens of flights. Elsewhere, a Ukrainian drone struck and heavily damaged a Russian supersonic bomber at an air base south of St. Petersburg. Meanwhile, the governments of Denmark and the Netherlands have pledged to give U.S.-made F-16 fighter jets to Ukraine, after the Biden administration recently gave approval to the transfers. On Monday, Ukrainian President Volodymyr Zelensky traveled to Copenhagen, where he spoke outside the Parliament to a large crowd of supporters.

President Volodymyr Zelensky: “Dear friends, today we are confident that Russia will lose this war.”

Zelensky’s trip comes as The New York Times reports the total number of Ukrainian and Russian troops killed or wounded in the 18 months since Russia invaded is nearing a half a million — a figure that doesn’t include civilian deaths and injuries. The Times cited unnamed U.S. officials for the figures, which estimate 120,000 Russian troop deaths and 70,000 Ukrainian soldiers killed in action.
