Rubio, after Lavrov talks, says Russia has also voiced interest in 'limited ceasefire'

By Tom Balmforth, Antoni Slodkowski and Simon Lewis UNITED NATIONS, Sept 23 (Reuters) - Ukraine and Russia have both voiced an interest in a limited ceasefire involving grain and energy-related targets, US Secretary of State Marco Rubio said on Wednesday after meeting Russian Foreign Minister Sergei Lavrov in New York. Ukraine and its allies have pressed for a moratorium in attacks on energy infrastructure and for guarantees on Black Sea shipping, fearing Russia could target power and heating facilities this winter.
