NATO's Stoltenberg Tells Russia's Lavrov to Pull Out of Ukraine

NATO Secretary-General Jens Stoltenberg said on Tuesday he had told Russian Foreign Minister Sergei Lavrov that Russia must withdraw all troops and heavy weapons from Ukraine and end its support for separatists. The western military alliance's chief added that he had informed Lavrov, after a meeting in Brussels, that he was concerned about the large number of military exercises carried out by Russia at short notice. NATO has repeatedly criticized Moscow's involvement in the Ukraine conflict and demanded it fully implement a Ukraine ceasefire agreement. Russia denies providing any troops or arms to support rebellion in eastern Ukraine.
