NATO Secretary General Jens Stoltenberg made a surprise visit to Ukraine’s capital Kyiv Thursday for talks with President Volodymyr Zelensky. During a joint press conference, Zelensky said it is time for NATO to invite Ukraine to join the military alliance. Stoltenberg replied that the issue would be discussed at a NATO summit in Vilnius, Lithuania, in July.

Jens Stoltenberg: “This will be high on the agenda of the meeting and also in the lead-up and the preparations for the Vilnius summit. Ukraine’s future is in the Euro-Atlantic family. Ukraine’s future is in NATO. All allies agree on that.”

This week, Ukraine received U.S.-made surface-to-air Patriot missile systems for the first time. Meanwhile, Russian officials have admitted that a Russian warplane bombed the city of Belgorod near Ukraine late Thursday after it accidentally fired a weapon. Russia’s Defense Ministry said some buildings had been damaged but no one was injured in the blast, which left a huge crater in a street near several apartment buildings.
