Ukrainian President Volodymyr Zelenskiy said on September 23 that he held an impromptu meeting in Ireland's Shannon Airport with the head of the Sudanese Sovereign Council, Abdel Fattah al-Burhan, and that they discussed Russian-funded armed groups. "We discussed our common security challenges, namely the activities of illegal armed groups financed by Russia," Zelenskiy said. He thanked Sudan, which is in the midst of a deadly civil war, for its support of Ukraine's territorial integrity. Russia's Wagner mercenary group has operated in Ukraine throughout Moscow's invasion. Western diplomats have said the group is also present in Sudan.
