An agreement by Ukraine and Russia for a 1,000-for-1,000 prisoner exchange is thought to be the only concrete result of peace talks in Istanbul which took place last week, which were the first such negotiations since 2022 when the ongoing war began. Russian President Vladimir Putin invaded Ukraine in February 2022.

Hundreds of people have been released in the largest prisoner exchange since the start of the Russia-Ukraine war. Both sides have agreed to release 1,000 people each — including soldiers and civilians — by the end of the weekend.
