SLAVIANSK Ukraine (Reuters) - Only one of the Ukrainian army checkpoints encircling the separatist stronghold of Slaviansk, where a military operation was in its third day on Thursday, was letting traffic through - most on its way out.
Beyond it, the sporadic boom of heavy artillery shelling in the northern outskirts punctuated an eerie calm in the mostly unscathed centre of the sun-drenched town, where residents on bicycles and pushing strollers weaved their way through rebel roadblocks of felled trees, sand bags and rusted cars.
