(ANSA-AFP) - BUCHAREST, NOV 30 - NATO chief Jens Stoltenberg warned Tuesday that Russia was using winter as a "weapon of war" against Ukraine, as Western allies meeting in Bucharest planned to help Kyiv mend its ravaged power grid. US Secretary of State Antony Blinken was to announce "substantial" financial aid to help Ukraine deal with damaged infrastructure on the sidelines of a meeting of NATO's foreign ministers. A senior US official said the assistance would "not be the end" and pointed out the Biden administration had budgeted $1.1 billion for energy spending in Ukraine and neighbouring Moldova. A Russian campaign of missile strikes has severely damaged Ukraine's energy infrastructure and plunged millions into darkness as the country braces against the first snows and chill winds of winter.
