ACTION IN THE UKRAINE – AT 10:36 A.M. ET:  The crisis that won't go away.  From Fox:

Ukrainian forces exchanged gunfire with a pro-Russia militia in an eastern city Sunday, according to Interior Minister Arsen Avakov.

The minister said one Ukrainian security officer was killed and five others were wounded. It was the first reported gunbattle in east Ukraine, where armed pro-Russia men have seized a number of law enforcement buildings in recent days.

Sky News reported that a group of up to 100 civilians gathered outside the police headquarters to express their support for the separatists. Sky also reported that gunmen also took control of a police station in the nearby city of Kramatorsk following a shoot-out.

Avakov said in a Facebook post that a Security Service officer was killed in Slovyansk, where the police station and local Security Service office were seized a day earlier by camouflaged armed men. He also reported an unclear number of casualties among the militia.

Avakhov wrote that "all security units" were involved in an "anti-terror operation" in an attempt to take back the building that had been seized Saturday and advised the city's residents to stay indoors and away from windows.

"There were dead and wounded on both sides," Avakov said in the post, according to Reuters.

COMMENT:  There are an estimated 40,000 Russian troops on the Ukrainian border.  The question is whether they will invade the Eastern Ukraine, which has pro-Russian elements.  The United States has warned Russia that there will be serious consequences if it does invade, but this administration doesn't exactly have high credibility when making threats.
