Russia has 7,500 troops in the east of the country, where pro-Moscow separatists have been fighting government troops for months, Ukraine's defense minister said.
  
"Unfortunately, the stabilization of the situation in the east of Ukraine does not depend only on us," Stepan Poltorak said in a statement posted on the ministry's website on Saturday. "The presence of 7,500 representatives of Russian armed forces in Ukraine destabilizes the situation and prevents us from stabilizing it."
  
Cash-strapped Ukraine also plans to "increase the strength of the armed forces" and boost levels of arms and equipment, Poltorak added. He pledged this would take place "in the nearest time" but did not give a more specific timeframe.
