More than 1,700 Africans are fighting for Russia in its war in Ukraine, Ukrainian Foreign Minister Andrii Sybiha said on Wednesday, adding that Moscow was using deception to trick them into fighting.

Speaking alongside his Ghanaian counterpart, Sybiha said that discussions were underway with governments across Africa to prevent their citizens from being drawn into such schemes.

Ghana will chair the African Union regional bloc next year.

"We clearly see that Russia is trying to drag African citizens into a deadly war," Sybiha told a news conference. "According to our data, there are currently over 1,780 citizens from the African continent fighting in the Russian army."

The African fighters came from 36 different countries spread across the continent, he added.

Russian authorities have denied illegally recruiting African citizens to fight in the armed forces.

However, reports of African men being lured into Russia with promises of jobs and ending up on Ukraine's front line have become more frequent in recent months, creating tensions between Moscow and some of the countries involved.

Ghana's Foreign Minister Samuel Okudzeto Ablakwa said that many of the Africans fighting for Russia were victims of deception, lured on the dark web with the promise of ordinary jobs.

"They have no security background. They have no military background. They have not been trained," Ablakwa said. "They were just lured and deceived, and then put on the frontlines."

Ablakwa expressed solidarity with Ukraine and called for a ceasefire to end the war, which marked its fourth anniversary on Tuesday.

He said that he would ask Ukrainian President Volodymyr Zelenskiy to release two Ghanaian prisoners of war, who were captured fighting for Russia.

Ghana would promote schemes to raise public awareness of trafficking networks that deceptively recruit for Russian forces during its presidency of the African Union, Ablakwa said.
