BRUSSELS (Reuters) - Russia has moved troops closer to the border with Ukraine and continues to support rebels in the country's east, NATO's chief said on Tuesday, after an election held by the pro-Russian separatists and condemned by Kiev and Western leaders.

Ukraine's president said Sunday's vote flouted terms of a plan to end a war that has killed more than 4,000 people, and that newly formed army units would be sent to defend a string of eastern cities against a possible new rebel offensive.
