Tuesday morning the North Sea Brent on the London Market jumped over $1 from Monday's closing to $67.65 per barrel. U.S. crude oil jumped $1.39 to a high of $60.32 per barrel. The rise is attributed to the stoppage of crude oil from the eastern Libyan oil port of Zueitina, due to protests. Other Libyan ports had already been closed since former dictator Muammar Gaddafi was deposed. Several Libyan oil fields and the main pipeline to the ports have been closed by recent protests.
