Ukraine says six of its soldiers were killed during an ambush by militants on Tuesday.
CNN reports the Ukrainian Defense Ministry called it a "terrorist attack." The network adds:
"The incident took place in the village of Oktyabrski in the Slovyansk region, about 20 kilometers from Kramatorsk, during 'a unit movement from the military base.' The location is in volatile eastern Ukraine.
" 'Our soldiers were attacked in an ambush. Terrorists attacked our land troops with grenades. The attackers were more than 30 people and set an ambush near the river,' the ministry said.
" 'After a long shootout, six soldiers of The Ukrainian Armed Services were killed,' the statement said.
"In another incident in eastern Ukraine, a separatist leader has been injured in a suspected assassination attempt, a spokesman said Tuesday, amid continuing turmoil in the wake of a controversial weekend referendum on independence."
