MOSCOW, Feb 17 (Reuters) - Russia and Ukraine exchanged 101 prisoners of war in their latest prisoner swap on Thursday (Feb 16), their authorities said.

"Aircraft of the military transport aviation of the Russian Aerospace Forces will deliver the released servicemen to Moscow for treatment and rehabilitation in medical institutions of the Russian Defence Ministry," the Russian ministry said.

Ukrainian President Volodymyr Zelenskyy's chief of staff posted images of scores of Ukrainian servicemen posing for a photograph after being released.

He said 100 troops and one civilian had been returned.

Nearly all had been defending the besieged southern city of Mariupol before it fell to Russian forces, Andriy Yermak said on Telegram.

Earlier this month, Zelenskiy said that since the start of the conflict last February, Ukraine had secured the release of 1,762 men and women from Russian captivity.
