Feb 4 (Reuters) - Ukraine and Russia traded almost 200 prisoners of war in a swap announced separately by both sides on Saturday, with the bodies of two British volunteers also being sent back to Ukraine. President Volodymyr Zelenskiy said in a video address that since the war started last February, Ukraine had secured the release of 1,762 men and women from Russian captivity. Yermak also said the bodies of British volunteer aid workers Andrew Bagshaw and Chris Parry had been sent back to Ukraine
