Russia has handed over the remains of 1,000 fallen Ukrainian soldiers to Ukraine, according to President Vladimir Putin's adviser Vladimir Medinsky in social media.
"As a result of the agreement reached in Istanbul, another 1,000 bodies of Ukrainian soldiers were handed over to Ukraine today", he writes on Telegram.
According to Medinsky, Ukraine simultaneously repatriated the remains of 19 Russian soldiers.
Exchanges of prisoners of war and fallen soldiers have taken place regularly during the war, but have increased after the largely unsuccessful peace talks in Istanbul earlier in the summer.
