NATO's top general says he has little faith in the 2-week-old cease-fire between Ukraine and pro-Russian militants fighting in the country's east.

Speaking to reporters in the Lithuanian capital of Vilnius (VEEL'-nee-oos) on Saturday, U.S. Air Force Gen. Philip Breedlove said the September agreement is a "cease-fire in name only." He said violence levels, including the number of artillery rounds fired in the past few days, are as high as prior to the cease-fire.

Breedlove said he hopes the agreement announced Saturday for creation of a buffer zone between Ukrainian government troops and the pro-Russian militants will succeed in stabilizing the situation.

Breedlove was in Vilnius for a meeting of NATO military chiefs, who discussed a range of issues including the situation in Ukraine and relations with Russia.
