Alexander Hug, deputy chief monitor of the OSCE monitoring mission to Ukraine, told Reuters by phone monitors had spotted the Buratino at a rebel training area in the village of Kruhlyk.
"We saw the weapon on that training ground," Hug said. "Both sides agreed a year ago to withdraw heavy weaponry from the line of contact. Having them near the line of contact is of course a concern as this weapon should be in storage and not be used."
