STORY: The defence ministry said 694 Ukrainian fighters - including members of the Azov regiment - had surrendered in the past 24 hours, including 29 wounded.
It said 51 of the fighters requiring medical assistance had been transferred to a hospital in Novoazovsk, some 25 miles east of Mariupol.
Top-ranking Ukrainian commanders at Mariupol's Azovstal steelworks are still inside the plant and have yet to surrender, local media quoted pro-Russian separatist leader Denis Pushilin as saying on Wednesday.
DAN news agency quoted Pushilin as saying that the hundreds of fighters who had given themselves up did not include any commanders of the highest level. "They have not left (the plant)" as of now, he said.
