Earlier, Poland had deployed two pairs of F-16 fighters and an allied tanker in the face of Russian attacks on Ukraine.
The Polish Army announced the move in a statement on Tuesday morning.
Poland's military command said that in the early hours of Tuesday, "two pairs of F-16 fighter jets and an allied oil tanker were activated" in order to "safeguard the Polish airspace."
The measures were taken due to an "intensive activity of the long-range aircraft of the Russian Federation," as part of "strikes on the territory of Ukraine," officials added.
It came after Russia launched a drone and missile attack on Ukraine, including Kyiv and Kharkiv, overnight into Tuesday, Polish state news agency PAP reported.
The missiles were fired from Russia's strategic Tu-95M bombers, according to news outlets.
Among the affected areas was Kyiv, where a minimum of 10 people have been reported injured, and Kharkiv, Ukraine's second-largest city, has also suffered.
The Ukrainian capital has resonated with a series of explosions, according to reports.
On Friday, an air object temporarily entered Polish airspace, during Russia's large-scale air assault on Ukrainian cities that killed 39 people.
The Polish Army later said the object was a "Russian cruise missile" that then left Polish airspace.
Readings from Polish and NATO radars, as well as a ground search carried out at the weekend, confirmed that the missile had left Polish territory, officials said on Tuesday.
Tuesday is day 678 of Russia’s war on Ukraine.
Russia invaded Ukraine on February 24, 2022, launching the largest military campaign in Europe since World War II.
