Ukrainian government forces are starting to pull Uragan multiple-launch rocket systems back from the contact line in the south-east of Ukraine in accordance with the February 12 agreements, the anti-terrorist operation spokesman Anatoliy Stelmakh told Interfax-Ukraine.

"The withdrawal of BM-21 Grad multiple-launch rocket systems took place yesterday and continued for 24 hours. The next stage of the withdrawal process - the withdrawal of Uragan systems - will begin on Friday. We have already brought journalists there to observe this process," he said.

Stelmakh told a press briefing earlier that the Ukrainian side was observing the ceasefire and was pulling heavy weaponry back from the line of contact.
