Oil falls below $49 on economic jitters, ample supply

By Alex Lawler LONDON (Reuters) - Oil fell below $49 a barrel on Tuesday, pressured by concerns that a potential slowdown in economic growth could sap demand and by persistent signs of abundant supply despite another militant attack on Nigeria's oil industry.
