NATO fighter jets shot down multiple Russian drones that violated Polish airspace during an attack on neighboring Ukraine early on Wednesday, as the military alliance denounced Moscow for “absolutely dangerous” behavior that ratcheted up tensions to a new level.

Russian drones shot down over Poland were reportedly headed for Rzeszow Airport, a key logistics hub for aid to Ukraine, German media outlets Spiegel and Welt reported on Sept. 11.

Russian drones bombed Kyiv, the capital of Ukraine, killing at least four people setting the city's main government building on fire.

WARSAW, Poland (AP) — Polish Prime Minister Donald Tusk pledged Thursday to push ahead with a “great modernization program” for his country’s military, a day after Russian drones crossed into Poland and amplified international tensions around Russia’s invasion of Ukraine, including what the Kremlin’s future territorial ambitions might be.

Analysts have linked major attacks to important geopolitical events as the Kremlin tries to strengthen its hand in talks.

KYIV, Sept 7 (Reuters) - Russia launched its largest air attack of the war on Ukraine overnight, setting the main government building on fire in central Kyiv and killing at least four people, including an infant, Ukrainian officials said on Sunday.

Gen. Oleksandr Syrskyi also said Ukrainian "deep strike" weapons hit 60 targets inside Russia last month.
