BERLIN, Shawwal 26, 1435, Aug 22, 2014, SPA -- Chancellor Angela Merkel said in two separate phone calls on Friday with Russian President Vladimir Putin and Ukraine President Petro Poroshenko that she was concerned that a Russian humanitarian aid convoy crossed into Ukraine without permission, Reuters cited her spokesman Steffen Seibert as saying. Seibert also said in a statement that Merkel had praised Ukraine's prudent reaction after she said Russia risked exacerbating an already tense situation there. She also appealed for quick agreements on a ceasefire and territorial integrity. "Chancellor Merkel expressed her great concern about the fact that the convoy had crossed the border without the approval of Ukraine, without accompanying by the Red Cross and in part without any previous inspection," Seibert said in a statement. -- SPA 21:28 LOCAL TIME 18:28 GMT www.spa.gov.sa/1265068
