Poland said it has activated its air force after Russia violated its airspace while carrying out a major missile attack on western Ukraine.
The Polish Armed Forces Operational Command said on X that a cruise missile entered Polish space in the early hours of Sunday near the town of Oserdów and remained there for 39 seconds.
They said the Polish military radar systems observed it for the entire flight.
The Command said that Polish and allied aircraft have been activated, which may increase noise levels in parts of the country.
Poland's army spokesperson, Jacek Goryszewski, said the missile traveled about 2 km, or 1.2 miles, into Polish airspace before returning to Ukraine, per Reuters.
The country said it would demand an explanation from Moscow, Reuters reported. Russia is yet to comment on the attacks.
Jacek Siewiera, the head of the Polish National Security Bureau, said on X that NATO allies had been informed of the incident.
Russia has conducted a major campaign of aerial attacks on Ukraine's capital Kyiv and the western region of Lviv in recent days.
Meanwhile, on Saturday, Russia launched 57 missiles and drones in the attacks on Ukraine, Reuters said, some of which struck critical infrastructure in the western city of Lviv and targeted the capital Kyiv.
Infrastructure in the city of Kryvyi Rih and the Odesa region in the south were also hit, the Kyiv Independent reported.
It is being described as the largest aerial bombardment of its energy system since the war began.
Moscow said that the attacks were retaliation for recent strikes inside Russia.
Ukrainian President Volodymyr Zelenskyy has urged Western allies to provide additional air defense systems and ammunition. At the same time, a $60 billion aid package from the US remains stalled in Congress.
