ISTANBUL, Turkey — The first direct Russia-Ukraine peace talks since the early weeks of Moscow’s 2022 invasion ended after less than two hours Friday, and while both sides agreed on a large prisoner swap, they clearly remained far apart on key conditions for ending the fighting.

One such condition for Ukraine, backed by its Western allies, is a temporary ceasefire as a first step toward a peaceful settlement. The Kremlin has pushed back against such a truce, which remains elusive.

“We haven’t received a Russian ‘yes’ on this basic point,” Ukrainian Foreign Ministry spokesman Heorhii Tykhii said after the talks. “If you want to have serious negotiations, you have to have guns silenced.”

But Russian delegation head Vladimir Medinsky pronounced himself “satisfied with the outcome,” adding that Moscow was ready to continue contacts.

Ukrainian President Volodymyr Zelenskyy said he discussed the talks with U.S. President Donald Trump and the leaders of France, Germany, the U.K. and Poland. In a post on X from a European leadership meeting in Albania, he urged “tough sanctions” against Moscow if it rejects “a full and unconditional ceasefire and an end to killings.”

Agree to Swap POWs

In Istanbul, Kyiv and Moscow agreed to exchange 1,000 prisoners of war each, according to the heads of both delegations, in what would be their biggest such swap.

Both sides also discussed a ceasefire and a meeting between their heads of state, according to chief Ukrainian delegate, Defense Minister Rustem Umerov.

Medinsky, an aide to President Vladimir Putin, said both sides agreed to provide each other with detailed ceasefire proposals, with Ukraine requesting the heads of state meeting, which Russia took under consideration.

“The pressure on the Russian Federation must continue,” said Serhii Kyslytsia, Ukraine’s first deputy foreign minister and part of Kyiv’s delegation. “We should not really relax at this point.”
