U.S. special envoy Steve Witkoff and President Donald Trump's son-in-law and advisor, Jared Kushner, are visiting Moscow and Kyiv over the weekend in an effort to end the war between Russia and Ukraine.

"We have an idea for peace," Trump told reporters on Friday. "I sent Steve Witkoff and Jared Kushner, two great negotiators. They've done a great job, and we sent them over to see whether or not we can get something done. And there may be a good chance that we'll do it," he said.

Ukrainian President Volodomyr Zelenskyy confirmed the news in a post on X.

"Today, it has been clearly established that U.S. envoys will be in Ukraine and Russia in the coming days. We have the details from the U.S. President’s team. We discussed today that Steve Witkoff and Jared Kushner will visit Moscow and then Kyiv on Sunday. We are preparing for the visit," Zelenskyy wrote.

The pair will visit Russia first on Saturday and, Russian drone strike targeted the Security Service of Ukraine’s headquarters in Ukraine, Zelenskyy wrote in a public message on the app Telegram.

Zelenskyy alleged the strike directly targeted the head of the Security Service's office.

He also wrote that he was directing the head, Oleksandr Poklad, to prepare a retaliatory strike. 

"I gave Poklad the task of adequately, noticeably and, if possible, mirroring the Russians' response to this attack, when everything is prepared. Our military will support this response. Glory to Ukraine!" Zelenskyy wrote.

At least nine people were injured in the explosion, Kyiv Mayor Vitali Klitschko also wrote on Telegram.

The visit also comes just one day after German officials formally accused Russia of attempting an explosive drone attack on a major airport in Germany.

"The attack on the aircraft in Leipzig was concrete; it could have triggered a catastrophe had it succeeded. The attacker was, at most, covert, but even here there is now certainty: The German government has named Russia as the mastermind. Patterns of attack, police investigations, and intelligence findings prove Russian responsibility for the drone attack," Stefan Kornelius, a spokesperson for the German federal government, wrote Friday.

Fox News Digital contacted the White House and the foreign ministries for Russia, Ukraine and Germany for further comment.
