The light L-159 fighter is likely the plane promised by president of Czech Republic, Petr Pavl, to Volodymyr Zelenskyy. What we know on day 1,424

The Czech Republic is set to provide Ukraine shortly with “medium combat planes which are highly effective in fighting drones”, President Petr Pavel told his Ukrainian counterpart, Volodymyr Zelenskyy, in Kyiv on Friday. 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. The Czechs’ main fighter jet is the Swedish Saab JAS-39 Gripen. 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 guarantees and Ukraine’s economic recovery, Kyiv’s ambassador to the US, Olga Stefanishyna, said on Friday. Zelenskyy said he hoped Ukraine would sign security guarantees with the US next week, possibly at the World Economic Forum in Davos. In Miami, Ukraine’s negotiators would be Kyrylo Budanov, head of the presidential office, and Rustem Umerov, Ukraine’s defence council secretary, the ambassador said, without naming the US participants. They would discuss security guarantees and postwar reconstruction. “The goal of the visit is to finalise these agreements with our American partners,” said Stefanishyna.

A majority of Ukrainians would strongly oppose withdrawing troops from the remainder of the Donetsk region still controlled by Kyiv in exchange for European and US security guarantees, a poll released on Friday indicated. The Kyiv International Institute of Sociology (KIIS) said 54% of Ukrainians categorically rejected the idea; 39% would reluctantly accept. “Those who are ready to agree expect quite significant security guarantees,” said KIIS executive director Anton Hrushetskyi. The survey was conducted in early January among 601 respondents on Ukrainian-controlled territory.

Almost 70% did not believe current negotiations would lead to a lasting peace, with 57% believing Russia would attack again if there was a ceasefire at the current frontlines and security guarantees from allies. Even if security guarantees were given, 40% believed the US would not provide support in the event of renewed Russian invasion, against 39% who thought it would. Russia has publicly shown little interest in scaling down its demands and made few comments regarding the 20-point peace framework that Ukraine and the US have been trying to finalise.

Russia and Ukraine on Friday agreed to a localised ceasefire to allow repairs on the last remaining backup powerline at the Zaporizhzhia nuclear power plant, according to the UN’s nuclear watchdog, the IAEA. Zaporizhzhia is the biggest nuclear power plant in Europe and has been illegally occupied by Russian forces since March 2022. Its six reactors have been shut down since the occupation but it still needs electricity to keep its nuclear fuel safely cooled.
