MOSCOW / KYIV - A meeting between Russian President Vladimir Putin, US President Donald Trump and Ukrainian President Volodymyr Zelensky is unlikely to take place anytime soon, Kremlin spokesperson Dmitry Peskov said Tuesday.

Peskov said that while the Russian leader remains open to holding high-level talks, he believes that such a meeting should only happen after agreements have been reached and worked out at the technical level.

Russian and Ukrainian delegations met in Istanbul on Monday for a second round of direct talks, during which the two sides agreed to a major prisoner swap, discussed humanitarian issues, and exchanged draft peace proposals outlining concrete terms for settling the Ukraine crisis.

"Of course, it would be wrong to expect any immediate decisions or breakthroughs," Peskov said when commenting on the latest meeting.

Peskov stated that certain important agreements were reached on Monday in Istanbul and that Moscow will await Kyiv's response to the peace memorandum that Russian officials handed to the Ukrainian side.

At the same time, he said that discussions about "compromises" in the draft proposals should be conducted directly with Kyiv, noting that the details would not be made public.

Meanwhile, the Security Service of Ukraine said Tuesday that it has hit the Crimean Bridge for the third time using underwater explosives.

About 1,100 kilograms of TNT-equivalent explosives were placed under the bridge and detonated at 4:44 local time (0144 GMT), it said in a statement on Telegram.

The blast caused damage to the bridge's underwater support pillars. There were no civilian casualties, the statement said.

"The Crimean Bridge is a completely legitimate target, especially considering that the enemy used it as a logistical artery to supply its troops," Vasyl Malyuk, head of Security Service of Ukraine, was quoted in a statement as saying.

According to a video published by the Russian Federal Security Service on Tuesday, a detained resident of the Crimean city of Feodosia admitted that he had made a bomb to commit a terrorist attack on orders from Kyiv.

Ukraine had carried out attacks on the Crimean Bridge in 2022 and in 2023.
