Polish foreign minister arrives in Kyiv
Radosław Sikorski, Deputy PM and Minister of Foreign Affairs of Poland, arrived in Ukraine on 12 September.
"Deputy Prime Minister, Foreign Minister Radosław Sikorski has begun his visit to Ukraine. He was welcomed at Kyiv’s railway station by Ukraine’s Foreign Minister Andrii Sybiha," the Polish Foreign Ministry wrote on X.
Sybiha, meanwhile, wrote on X (Twitter) that the two countries "stand firmly together" amid Russia’s escalation of terror against Ukraine and provocations against Poland.
"Welcome to Kyiv, Radek! [...] We will hold substantial talks today about our shared security, Ukraine’s EU and NATO accession, and pressure on Moscow. I thank Poland for its leadership and support," Sybiha wrote.

The outlet notes that Sikorski’s visit comes two days after Russian drones made an unprecedented violation of Poland’s airspace.
On 11 September, Polish Prime Minister Donald Tusk said that Poland had agreed to meet with the Ukrainian side and would work together with Ukraine to maximise defence against Russian drones.
Reuters reported that representatives of the Polish armed forces will travel to Ukraine to learn techniques for shooting down drones.
