Oil falls to $49 on economic concerns, ample supply

By Alex Lawler LONDON (Reuters) - Oil fell below $50 a barrel on Tuesday on concerns that a potential slowdown in economic growth could sap demand and persistent signs of abundant supply despite another militant attack on Nigeria's oil industry. Brent crude was down $1.21 at $48.89 a barrel at 1140 GMT. "Asia has been relatively weak and China is not providing much support," said Olivier Jakob, oil analyst at Petromatrix, who also said weak refined products were pressuring crude.
