Serbs in the ethnically divided city of Mitrovica in northern Kosovo erected new barricades on Tuesday, hours after Serbia said it had put its army on the highest combat alert following weeks of escalating tensions.Asked about Kosovan Interior Minister Xhelal Svecla's claim that Serbia, under the influence of Russia, was aiming to destabilise Kosovo by supporting the Serb minority, Kremlin spokesman Dmitry Peskov said it was "wrong" to search for a destructive Russian influence."Serbia is a sovereign country and it is absolutely wrong to look for Russia's destructive influence here," Peskov said.Serbian President Aleksandar Vucic said on Tuesday that Serbia would "continue to fight for peace and seek compromise solutions.""Having very close allied relations, historical and spiritual relations with Serbia, Russia is very closely monitoring what is happening, how the rights of Serbs are respected and ensured," Peskov said."
