MINSK, Sept. 29 - Ukraine and pro-Russian separatists have agreed to extend a pull-back of weapons in east Ukraine to include tanks and smaller weapons systems, the OSCE's representative at peace talks, Martin Sajdik, said on Tuesday, Reuters reported.

The deal was agreed during further talks in Minsk, Belarus, on the ceasefire, whose implementation has faced regular setbacks due to accusations from both sides of violations.
