Donetsk, Ukraine (CNN) -- Long lines of cars jammed the roads leading south out of Donetsk in eastern Ukraine Saturday, as residents attempted to flee the city center after a night of heavy shelling on the city's northern outskirts. Hundreds of vehicles were caught in heavy traffic, and trains are no longer running in and out of the city, which is a stronghold for the pro-Russia rebels. There was heavy shelling and antiaircraft fire on the outskirts of the city to the north throughout the night. There has been sustained fighting in the area for weeks, but it appeared more intense overnight than in recent days.
