Diplomats from US, Ukraine and European nations are set to hold a meeting in London on Wednesday in their bid to establish a peace deal between Kyiv and Moscow. The meeting is followed by discussions in Paris last week that would ascertain the possibilities of a ceasefire and how a long-term peace deal can be achieved. The meeting was earlier supposed to involve foreign ministers but was revised overnight. The US Secretary of State Marco Rubio would be unable to mark his presence due to a scheduling issue.
