MOSCOW (Reuters) - Russian President Vladimir Putin called on Friday for a ceasefire by pro-Russian separatists and Ukrainian government forces fighting in eastern Ukraine to allow for negotiations. "Direct talks between the opposing sides must be established as soon as possible. All sides in the conflict must swiftly halt fighting and begin peace negotiations," Putin said at a meeting with Russian Orthodox Church leaders.
