Pavel has previously said Czech-made subsonic L-159 fighter jets could be transferred to Ukraine. “I believe we will manage to quickly and successfully conclude this issue,” Pavel told a news conference with Zelenskyy.The Czech army has 24 one- and two-seater L-159 jets, used for training and support for ground forces. They can be armed with missiles and machine-gun pods. Iraq used the jets in the war against Islamic State, and fleets are owned by private companies that loan them to the US and UK air forces for combat training.

Pavel said Prague might also supply early-warning systems such as radars.Zelenskyy meanwhile conceded problems with Ukrainian air defences at a critical moment in the war. Some systems supplied to Ukraine by western allies had run out of ammunition amid a wave of Russian attacks that have devastated his country’s energy infrastructure. “Until this morning we had several systems without missiles. Today I can say this openly because today I have those missiles … We received a substantial package in the morning.” He urged both European allies and the US to increase deliveries.Ukraine and the US will hold talks in Miami on Saturday to discuss security
