Kiev, Ukraine (CNN) -- A perilous face-off intensified Saturday when Russia state news complained that Ukraine had mobilized 15,000 troops in the suburbs of Slavyansk in eastern Ukraine "in order to wipe out the city and its residents." Quoting a Russian Defense Ministry source, RIA Novosti said satellite photos showed the force forming around the city that has become a friction point between the Ukraine military and pro-Russian militants. The Defense Ministry source said the number of Ukraine troops put the pro-Russian militants at a disadvantage because the latter are "armed only with small amount of pistols and shotguns." Many eastern Ukraine residents have Russian roots and sympathize with Moscow.
