Ukraine’s President Volodymyr Zelensky and Polish Prime Minister Donald Tusk have met in Warsaw, where the pair signed a security agreement between their two countries, Paralel.Az reports citing Notes from Poland.

The document includes measures on training a “Ukrainian legion” in Poland and on ambitions for Poland to shoot down Russian missiles and drones over Ukraine that are heading towards Polish airspace.

At the end of June, Tusk revealed that he would meet with Zelensky before the NATO summit in Washington, which will start tomorrow. However, the fact that the meeting would take place in Warsaw today was only announced this morning.

Poland is the latest in a series of countries to sign security agreements with Ukraine, pledging to maintain long-term support for Kyiv’s defence against Russian aggression. Last month, the United States and Japan became the 16th and 17th countries to sign such deals.
