Ukrainian President Volodymyr Zelensky said on Sunday that Ukraine's talks with US peace negotiators Steve Witkoff and Jared Kushner were "very productive." Zelensky told reporters that the discussions covered security and economic guarantees for Ukraine, in addition to supplies of air defense missiles and a winter support package. He also expressed hope that trilateral talks involving Ukraine, Russia, and the United States would resume soon. He added that despite a "positive assessment" of the talks, the war with Russia "currently" looks likely to continue through the coming winter. Zelensky said: "We very much hope that we will be able to reach agreements with our American partners, and we are counting on the support of our European partners if the war continues in the winter, and this is what the situation looks like right now. But nonetheless, the teams today have a positive assessment of our future prospects." He considered that the issue of territories, which lies at the core of the conflict between Ukraine and Russia, can only be resolved through meetings between heads of state. He said: "I maintain my position that such complex issues (connected to territories) can only be resolved at the leaders' level." Zelensky has long called for a meeting with his Russian counterpart Vladimir Putin, something the latter rejects. For his part, Witkoff said he is optimistic about peace talks in both Moscow and Kyiv, adding that the United States hopes to reach a diplomatic solution to the war, which has now entered its fifth year. He added: "Russia and Ukraine must make concessions to end the war." Witkoff and Kushner began talks on Sunday in Kyiv, where they arrived carrying, according to President Donald Trump, a proposal to put an end to the war with Russia, the day after meeting President Vladimir Putin in Moscow. This is the first visit by Witkoff, a businessman close to Trump, and Jared Kushner, the US president's son-in-law, to Ukraine since they began mediating this conflict. The envoys arrived by train at the Kyiv central station, after their plane landed at dawn on Sunday in the Polish city of Rzeszow near the Ukrainian border, according to the Flightradar24 flight tracking website. They then began talks with President Zelensky, who announced this on his social media accounts, publishing a video showing him shaking hands with the envoys and then visiting St. Sophia's Cathedral in Kyiv with them. The Ukrainian president told reporters shortly before the arrival of the US envoys that a round of talks within the framework of this visit will be attended by "European national security advisers." Zelensky had written in recent hours on social networks: "Ukraine has always shown a constructive position and will continue to do so. We wish to speed up the cessation of the war. Peace is necessary. And it is necessary to provide security guarantees." He added: "Our proposals are ready. It is important to work in a coordinated, in-depth, and realistic manner." Since returning to the White House in early 2025, Trump has launched rounds of talks seeking a settlement to end the most violent conflict in Europe since World War II, but these attempts have not yet achieved any tangible progress, particularly as Washington's focus shifted to the war with Iran. Negotiations are stumbling mainly over the issue of territories, as Moscow demands the complete withdrawal of Ukrainian forces from the Donetsk region (east) and its cession, which Kyiv rejects. "A number of ideas" Putin held three hours of talks on Saturday evening with Witkoff and Kushner, which Kremlin aide Yury Ushakov described as "constructive, very frank, and characterized by trust." Ushakov told reporters that the US envoys "presented a number of ideas on possible ways to reach a settlement." He stressed that the Russian side "expressed confidence in achieving the set goals," without revealing them. In contrast, a White House spokesperson said that the envoys discussed with Putin "substantive plans regarding upcoming steps that will be announced in subsequent weeks." Trump said that the negotiators will seek to explore the possibility of making progress toward peace, without revealing whether the plan includes Kyiv ceding regions to Russia, as he previously hinted, contenting himself with saying, "We have an idea for peace." On the occasion of this visit, Putin ordered a halt to strikes on Kyiv for three days from Saturday to Monday, while Zelensky for his part announced a halt to attacks on Moscow during the same period. Meanwhile, strikes continue in other locations in Ukraine and Russia. Moscow attacked Ukraine on the night of Saturday-Sunday with 108 drones and missiles, which the Ukrainian air force confirmed it intercepted most of while 11 targets were hit. In contrast, the Russian army announced the downing of 258 Ukrainian drones launched at Russia the previous night. A fire broke out at a facility in the city of Ryazan, according to the regional governor, while the "Astra" media outlet confirmed it was a refinery. At least three civilians were wounded in Ukraine in strikes that took place overnight and on Sunday morning, according to local authorities, while a man was killed and a woman was injured in a Ukrainian drone attack that hit their car in Russia's Belgorod region, according to local authorities.
