DUBAI, United Arab Emirates (AP) — Ukrainian President

Volodomyr Zelenskyy

arrived in Saudi Arabia on Tuesday with plans to visit the kingdom's powerful crown prince to push for a

peace plan

and the return of

prisoners of war

from Russia.

Saudi Crown Prince

Mohammed bin Salman

has sought to position himself as a potential mediator to end

the war between Ukraine and Russia

— even as Riyadh remains closely aligned with Russia on energy policies through the OPEC+ group of countries.

Zelenskyy's trip came as Kyiv’s forces are slowly

being pushed back

in eastern Ukraine. Russia has gained the initiative due to its big advantage in troop numbers and weapon supplies, military analysts say, as Kyiv waits for news of new provisions from its Western partners.

The Ukrainian military said Tuesday it has withdrawn its forces from two more villages near

Avdiivka

in the eastern Donetsk region following intense overnight fighting, according to a Ukrainian army spokesman.

Ukrainian troops have pulled back from Sieverne and Stepove, Dmytro Lykhovyi said on national television. The two villages had a population of some 100 people in total before the full-scale invasion, he said.

Ukraine continues to “rely on Saudi Arabia's ongoing active support” in pushing forward with what has been described as a “Peace Formula” to end the full-scale invasion, which marked its

second anniversary

over the weekend, Zelenskyy said in a message on X, formerly Twitter.

Zelenskyy has presented a 10-point peace formula that, among other things, seeks the expulsion of all Russian forces from Ukraine and accountability for

war crimes

— at a time when the two sides are fighting from largely static positions along a roughly 1,500-kilometer (930-mile) front line. Such ideas are rejected out of hand by Moscow.

“The second topic is the return of POWs and deportees,” Zelenskyy wrote. “The kingdom’s leadership has already contributed to the release of our people. I am confident that this meeting will also yield results.”

He didn't elaborate on that, but said that economic cooperation also would be discussed.

The state-run Saudi Press Agency said that Zelenskky arrived at Riyadh’s King Khalid International Airport and was met by government officials.

Over the last several years, Crown Prince Mohammed over the last several years has reached

a detente with Iran

, pursued a peace deal with

Yemen's Houthi rebels

and also offered himself as a leader in other crises worldwide. That's after facing widespread international condemnation for the

Saudi-led war in Yemen

and the 2018

killing of Washington Post columnist Jamal Khashoggi

, which U.S. intelligence agencies believe was carried out on his orders.

In May,

Zelenskyy traveled to Saudi Arabia

for a meeting of Arab leaders and also met then with Crown Prince Mohammed. Saudi Arabia, the United Arab Emirates and Qatar — all neighbors on the Arabian Peninsula — have been involved with prisoner exchanges since the war broke out in 2022.
