Donald Trump spoke with Vladimir Putin for more than an hour on Wednesday, but admitted that negotiations would not lead to "immediate peace" in Ukraine and warned that Russia would respond to a successful attack on its airport this week.

According to his description of the discussions on his truth social platforms, the U.S. president has repeatedly claimed that he could end the Ukrainian war within 24 hours of his campaign and has not tried to stop the revenge of the Russian leader. He noted that Putin had proposed negotiations with Iran about his nuclear program, and Trump claimed that Tehran had been "walking slowly."

Putin once again ruled out a full ceasefire in Ukraine in his separate speech on Wednesday, claiming that it would only give Kiev time to regroup and regroup and regroup, while Ukraine's Volodymyr Zelenskyy described Moscow's peace proposal, which was proposed earlier this week as "nothing more than "the final end."

Comments from the two leaders confirmed that there was no progress in a truce in negotiations in Istanbul on Monday, but both sides expressed progress on other issues, including the transfer of captives and bodies.

Russia said it was "working" in the return of more than 300 Ukrainian children kidnapped by invading forces by the Kiev government and the International Criminal Court (ICC). It also confirmed that prisoner exchanges will take place in the coming days and discussions are underway about plans to repatriate thousands of fallen soldiers from both sides.

Zelenskyy said he hopes to exchange 500 prisoners of war this weekend, but said Russia's broader peace proposal in Istanbul equals "from the Russian side to our last atum".

Ukrainian officials immediately said they needed more time to study documents handed over by the Russians, but news reports at the time said it was just a reaffirm of Russia's biggest demand that Ukrainian forces withdraw from four areas under partial Russian occupation.

Putin expressed his position on Wednesday in the form of a virtual TV conference with his aides.

After learning that Ukraine had proposed an unconditional ceasefire of 30 to 60 days, Putin asked: "Why should they be rewarded by taking a break in the battle, which will be used to pump the regime with Western weapons to continue forcing mobilization and preparing for different acts of terror?"

He noted that one of Ukraine's recent attacks on Russian internal bridges helped kill seven people by causing a train crash.

Ukraine also launched a remote-controlled large-scale drone attack on four Russian airports on Sunday, with Kiev claiming that Ukraine defeated more than a third of Moscow’s heavy bombers and was able to launch cruise missiles.

Ukrainian officials said 41 Russian fighter jets and other types of fighter jets, including strategic bombers, were destroyed or damaged during Sunday's operation, which they claimed would take 18 months to plan. On Wednesday, they released other drone footage of the attack, codenamed Operation Cobweb.

Satellite photos analyzed and published by the Associated Press show that the Belaya Base in the wreckage and the burnt area is one of four airports targeted. It said the images show that at least three TU-95s and four Tu-22m bombers (all capable of launching cruise missiles) were destroyed on the runway. The other aircraft at the base were unscathed.

Trump said in his Truth Social Post that the drone attack on Russian airports was in an hour and 15-minute conversation with Putin on Wednesday.

"We discussed Ukraine's attack on Russian docked aircraft and various other attacks on both sides," Trump said. "It was a good conversation, but not a conversation that would lead to peace. President Putin did say, and it was very strong, that he would have to respond to the recent attack on the airport."

A Kremlin spokesman said Trump told Putin that Ukraine did not inform him before the drone attack.

Based on Russia's claims and Ukraine's open mapping, Russia stepped up its air strikes on the city ahead of negotiations in Istanbul, furthering the northern Sumi region of northern Ukraine, occupying 150 square kilometers (58 square miles) of the region in less than two weeks.

In his campaign, Trump claimed he could end the Ukrainian conflict more than 50 times in one day, but his comments on Wednesday did not involve any restrictions. Instead, he noted that Putin has helped in direct negotiations, and the United States has been conducting a nuclear program with Iran, which has since 2018 has gone beyond a multilateral agreement to limit its restricted sanctions relief.

Although Putin ruled out a full ceasefire, Russia recommended two to three days of local struggle in different areas of the frontline to allow opposition troops to collect the dead, Moscow said Kiev refused.

However, both sides indicated on Wednesday that they were ready to continue exchanging prisoners of war, dead soldiers' bodies and provide some cooperation on Kiev's priorities (the return of Ukrainian children).

During a video government meeting on Wednesday, Istanbul's chief Russian negotiator Vladimir Medinsky said Russia "worked" in the return of Ukrainian children, noting that Kief had listed 339 of them.

Russia claims Ukrainian children were taken to Russia for security, while Kiev insists they have been kidnapped. Ukraine’s view is based on the International Criminal Court (ICC), which issued a warrant for Putin and his “Child Rights Commissioner” Maria Lvova-Belova in March 2023 for their role in the “illegal deportation” of Ukrainian children.

After the Istanbul meeting, Zelenskyy said that his delegation had already put a list of names of nearly 400 kidnapped Ukrainian children, but claimed that Russia only proposed to resolve 10 of the cases.

After Monday's talks, Türkiye's leader Recep Tayyip Erdoğan announced that he wanted to host a Putin-Zelensky summit involving Trump. Zelenskyy has been challenging his Russian counterparts to face him for months.

"We are ready for the daily meeting," the Ukrainian leader said on Wednesday, adding that further negotiations with Russian delegates in central Putin were "meaningless" as Putin had sent out negotiations - Zelensky had previously been seen as "shorts" because they did not have the right to agree to a ceasefire.

But Putin insisted on opposing a private meeting with Zelenskyy, but he called it a "act of terror" due to the recent attack on railways in the Kursk and Bryansk border areas.

"How do you do any such (summit) meeting in this case? What are we going to talk about?" Putin asked during a video call with officials.

Since Trump returned to the White House in January, the European capital has tried to play more leadership in strengthening Ukraine's defense, announcing a series of military industrial support measures, jointly chaired by the UK and Germany, at a meeting of the powerful Ukrainian defense liaison team at the NATO headquarters in Brussels on Wednesday.
