PARIS, Jan 6 (Reuters) - The United States for the first time on Tuesday backed a broad coalition of Ukraine's allies in vowing to provide security guarantees that leaders said would include binding commitments to support the country if Russia attacks again.
The pledge came at a summit in Paris of the "coalition of the willing" of mainly European nations to firm up guarantees to reassure Kyiv in the event of a ceasefire with Russia, which invaded its neighbour in 2014 and again at full scale in 2022.
