BERLIN, Shawwal 10, 1435, Aug 6, 2014, SPA -- Russia must avoid any action that could result in the Ukraine crisis escalating further, Reuters quoted a spokeswoman for the German foreign ministry as saying on Wednesday. "We demand the greatest possible transparency and we call on Russia to refrain from taking any steps that lead to a further escalation - that could be a combination of military exercises and troop concentrations," the spokeswoman said. --SPA 13:41 LOCAL TIME 10:41 GMT www.spa.gov.sa/w
