KIEV, Dec. 27 - Ukrainian authorities and separatists exchanged hundreds of prisoners of war on Friday, a spokesman for President Petro Poroshenko said, part of a 12-point plan aimed at ending the pro-Russian uprising in the east of the country, Reuters reported.

The agreement to swap 150 Ukrainian servicemen for 222 rebels followed peace talks between envoys of Ukraine, Russia, the separatists and European security watchdog Organization for Security and Co-operation in Europe (OSCE) on Wednesday.
