Brussels, Shawwal 10, 1435, Aug 6, 2014, SPA -- The Russian military build-up at the border with Ukraine is creating a "dangerous situation," dpa cited NATO as warning. "We're not going to guess what's on Russia's mind, but we can see what Russia is doing on the ground - and that is of great concern," NATO spokeswoman Oana Lungescu said in a statement, noting that approximately 20,000 combat-ready troops have been amassed. --SPA 14:34 LOCAL TIME 11:34 GMT www.spa.gov.sa/w
