Przewodow, Poland (AP) The NATO chief and the president of Poland both say there are no indications a missile that came down in Polish farmland, killing two people, was a deliberate attack. They said that Ukraine likely launched the Soviet-era projectile as it was fending off a Russian air assault that savaged its power grid. The missile came down Tuesday as Russia launched missiles and exploding drones. Poland said the missile was Russian-made. U.S. President Joe Biden said it was “unlikely” that Russia fired it. Three U.S. officials said preliminary assessments suggested it was fired by Ukrainian forces at an incoming Russian missile.

KYIV, Ukraine (AP) — Poland says a Russian-made missile fell in the eastern part of the country, killing two people in a blast that Ukrainian President Volodymr Zelenskyy decried as “a very significant escalation” of the war. Serious questions about the explosion remain, including who fired the missile. U.S. President Joe Biden said it was “unlikely” that the missile was fired from Russia, but he convened an emergency meeting of the Group of Seven and NATO leaders who were in Indonesia for another summit. It was not immediately clear whether Biden was suggesting that the missile hadn’t been fired by Russia at all. Russia denied any involvement. Biden pledged support for an investigation Poland said it was conducting.
