MOSCOW - Russia continues work on arranging a fresh prisoner swap with Ukraine and favors an all-for-all exchange, Kremlin spokesman Dmitry Peskov said on Friday, after the government in Kiev said a large-scale swap could happen as early as next week. Peskov also said work was under way to set the date for a 'Normandy Four' summit on Ukraine following a breakthrough in peace talks this week, but no specific timeframe has been agreed so far.
