A "Russian-made missile" landed in Poland near its border with Ukraine on Tuesday and killed at least two people, the Polish Foreign Ministry said in a statement.
State of play: Russia has denied any responsibility for the explosion in the Polish village of Przewodów, saying "no strikes were made against targets near the Ukrainian-Polish state border by Russian means of destruction," according to state media.
The latest: President Biden, who is in Indonesia for the G20 summit, said he and the leaders of eight allied countries had agreed during an emergency meeting to support Poland's investigation into the explosion.
Stoltenberg will chair an emergency meeting of NATO ambassadors on Wednesday "to discuss this tragic incident," a spokesperson for the alliance said.
The big picture: Russia struck several Ukrainian cities and energy facilities with a massive barrage of missiles on Tuesday, including its capital of Kyiv.
What they're saying: A White House National Security Council spokesperson said earlier Tuesday that the U.S. was "working with the Polish government to gather more information."
Watch to watch, via Axios' Dave Lawler: As a NATO member, Poland is covered by the Article 5 guarantee that an "armed attack" on it shall be considered an attack on all allies, who will respond accordingly.
