SLOVYANSK, Ukraine (AP) - Ukraine's interior minister says one security officer has been killed and five others have been wounded in a gunfight with pro-Russian militia.
Arsen Avakov says in a Facebook post Sunday the Security Service officer was killed in Slovyansk where a police station was seized by camouflaged armed men.
An Associated Press reporter on the ground didn't see any unrest there when he arrived.
The unrest in Slovyansk and the nearby major industrial city Donetsk are the latest signs of spiraling anger in eastern Ukraine, which has a large Russian-speaking population that fears it will be suppressed.
Meanwhile, Secretary of State John Kerry has expressed strong concern that attacks by armed militants in eastern Ukraine have been orchestrated and synchronized, and are similar to previous attacks in eastern Ukraine and Crimea.
The State Department says that Kerry spoke by phone with Russian foreign minister, Sergey Lavrov.
