Political developments in eastern Ukraine have for weeks been dominated by a small, vocal and armed opposition to the interim government in Kiev. The rallies yesterday, by contrast, drew crowds who listened to speeches condemning Russia and resisting the pro-Russian movement that is pushing for autonomy for eastern Ukraine.
Rallies were held in Donetsk, Luhansk, Mariupol and Kramatorsk, where key government buildings have been occupied by pro-Russian groups.
"Let those who have weapons be afraid of us, we will fight back. Let the ones who want to split up our country be afraid, because we won't allow them to do it," Lyashko said.
Hromadske television reported that police in Kramatorsk managed to thwart an attempt by pro-Russian activists to attack a pro-unity rally of about 500 people.
Ukraine's Interior Ministry said shots fired by servicemen in the base initially proved insufficient to deter the mob. There were no casualties among Ukrainian servicemen, the ministry said. At least 63 people involved in the attack were detained, but local media cited police as saying 38 were later released.
Associated Press video filmed outside the base on Wednesday night showed an unidentified man coming out to speak to the armed masked men, who said they wanted no bloodshed. A short while later, however, a crowd of mainly masked young men armed with bats and sticks began throwing Molotov cocktails at the base's gate and the trucks parked in front of it. Sounds of gunfire were heard in response.
