Leaders of several African nations arrived in Ukraine on Friday on a diplomatic tour aimed at encouraging peace negotiations and highlighting the impact of the conflict on their continent. The group, led by South African President Cyril Ramaphosa, traveled by train from Poland to Kyiv. He and officials from Senegal, Egypt, Zambia and the Comoros later toured the town of Bucha, visiting a church and the site of a mass grave. Ukrainian officials said in statements that Ukrainian forces shot down Russian missiles fired at Kyiv as the delegates arrived.
