Washington, 2 July 1999 (RFE/RL) - NATO's supreme commander, General Wesley Clark, says there is evidence that Yugoslav President Slobodan Milosevic is reinforcing his forces in Montenegro in preparation for a possible move against it's government. Clark made his comments yesterday during a press briefing in Washington. Clark said Montenegro remains what he called a "very sensitive area." He said he thinks Milosevic is calculating what moves will be to his best advantage in Montenegro, the small republic which along with Serbia makes up the Yugoslav Federation. Clark also said there has been a pattern by Milosevic of attempting in recent weeks to put ethnic Serbs and supporters of Montenegrin President Milo Djukanovic's political enemy Momir Bulatovic into positions of authority in Montenegro. Clark did not say what the NATO response would be if Milosevic moves against Montenegro.
