Russia could take steps of "a technically military nature" if its objections to NATO's planned missile defence system are not heeded, Russian Foreign Minister Sergei Lavrov told a Serbian daily Tuesday. "If our partners in the future continue to ignore out position we should protect our interests by other means... Concrete mesures might be needed... a response of a technically military nature," Lavrov told Belgrade's Vecernje Novosti in an interview published Tuesday. "We would not wish such a development," he added. Lavrov made his comments in light of the deal signed mid-September between Washington and Serbia's neighbour Romania to host US missile interceptors.
