Six African leaders plan to travel to Russia and Ukraine "as soon as possible" to help find a resolution to the war, South African President Cyril Ramaphosa has said, AFP reports.

"Russian President Vladimir Putin and Ukrainian President Volodymyr Zelensky have agreed to receive the mission and the African heads of state in both Moscow and Kyiv,” Ramaphosa said.

Ramaphosa said he had held "separate telephone calls" with Putin and Zelensky over the weekend, where he presented an initiative drawn up by Zambia, Senegal, the DR Congo, Uganda, Egypt and South Africa.

"I agreed with both Putin and Zelensky to commence with preparations for engagements with the African heads of state," Ramaphosa said.

"We&039;re hoping we will have intensive discussions," he said, speaking at a press conference in Cape Town during a state visit by Singapore Prime Minister Lee Hsien Loong.

"UN Secretary-General Antonio Guterres and the AU have been briefed on the initiative and welcomed it,” Ramaphosa added.

He did not give a specific timeline for the visit or other details, saying only that the conflict had been "devastating" and Africa "is also suffering a great deal" from it.

African countries have been badly hit by rising prices of grain and by the impact on world trade.

The announcement came a day after Ramaphosa said South Africa had been under "extraordinary pressure" to pick sides in the conflict, following accusations from the US that Pretoria supplied weapons to Moscow -- a move that would break with its professed neutrality.
