Oil falls below $50 on economic concerns

By Alex Lawler LONDON (Reuters) - Oil fell below $50 (£37) a barrel on Tuesday as concern about a potential slowdown in economic growth that would weigh on demand trumped supply outages in Nigeria and other exporting nations. Brent crude was down $1.04 at $49.06 a barrel at 0847 GMT (0947 BST). "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.
