Crude oil futures see-sawed in volatile trading today after dropping to six-week lows as the economic outlook remained gloomy.
On Thursday, oil slid more than 4% on recession fears the day after the US Federal Reserve warned of significant risks facing the world's top economy.
Brent crude has fallen nearly 7% from a week ago, pressured by uncertainties about the euro zone debt crisis, while US crude has dropped more than 8% as investors worried about the weak economy.
This evening in London, Brent crude was off 38 cents at $105.22 a barrel, after dropping to $103.43, the lowest level since August 10. US crude was down 44 cents at $80.07, after hitting a session low of $77.55, the lowest since August 9.
