NEW YORK, Dec 6 (Reuters) - U.S. crude futures fell on
Thursday, as a lowered growth forecast for the euro zone
reinforced worries about demand for petroleum and strengthened
the dollar and uncertainty about budget talks in the United
States continued to stoke investor caution.
U.S. January crude fell $1.62, or 1.84 percent, to
settle at $86.26 a barrel, having traded from $85.68 to $88.23.
