Polish and allied aircraft were deployed in a "preventive" operation across Poland's airspace on Saturday, prompting the temporary closure of Lublin airport, amid concerns over potential drone strikes in neighbouring Ukrainian regions.

A swarm of Russian drones flew last week into Poland in what officials there regarded as a deliberate provocation.

Ukraine uses SpaceX's Starlink for communications and to gather intelligence, but faced some issues with the system on Monday.

The idea of establishing a no-fly zone over Kyiv’s airspace was originally pitched by Ukrainian President Volodymyr Zelensky after Russia’s full-scale invasion in 2022.

Responding to President Trump, Poland's leader said, "we would also wish that the drone attack on Poland was a mistake. But it wasn't."

The UK is planning to mass-produce thousands of interceptor drones for Ukraine to help it defend itself against Russia's growing attacks.

The Kremlin's apparent efforts to probe NATO in Europe -- and that it feels emboldened enough to make them -- is dangerous. Poland triggered NATO's Article 4, which calls for urgent consultations and European leaders have suggested they are formulating how to boost air defenses.
