Niger has cut diplomatic ties with Ukraine, a move which signals a burgeoning rift between some West African states and Kyiv.

Niger’s military government said it made the move in “solidarity” with neighbouring Mali, who severed their own relations with Ukraine two days ago.

Both countries cited comments by a Ukrainian military official, who suggested Kyiv played a role in the killing of dozens of Malian soldiers last month.

Ukraine has been trying to win allies in Africa throughout its war with Russia, likely in an attempt to counter Moscow’s growing influence on the continent.

At the end of July, scores of Malian soldiers, along with mercenaries from Russia’s Wagner group, were killed in clashes with separatist rebels and al-Qaeda-linked militants.

Mali’s military regime had turned to the notorious Wagner group in 2021, seeking support in tackling its crippling insecurity issues.

After Wagner confirmed “losses” in July’s attack, Andriy Yusov, a spokesman for Ukrainian military intelligence, said the rebels received “the necessary information they needed” to conduct the attacks. He did not elaborate.

In response to Mr Yusov’s comment, Mali accused Ukraine of violating its sovereignty and announced it was breaking off relations with Ukraine “with immediate effect”.

Niger followed suit on Tuesday, with government spokesman Amadou Abdramane calling Mr Yusov’s remarks “unacceptable”.

Mali’s neighbour Senegal also rebuked Ukraine.

Over the weekend, Senegal’s foreign ministry summoned Ukraine’s ambassador, Yurii Pyvovarov, accusing him of supporting July’s attack in Mali in a since-deleted video posted on the Ukrainian embassy’s Facebook account.

Ukraine’s foreign ministry has not yet commented on Niger’s decision to sever diplomatic ties.

However, it called Mali’s decision “short-sighted and hasty”, and said Ukraine “unconditionally” complies with international law and accused Russian-controlled outfits of “numerous war crimes” in African countries.

Russia weighed in on the matter on Wednesday, accusing Ukraine of opening a “second front” in Africa.
