Jan 10 (Reuters) - U.S. stock index futures extended

losses on Friday after a better-than-expected non-farm payrolls

report for December ignited worries that the Federal Reserve

will be cautious in cutting interest rates this year.

A Labor Department report showed the U.S. economy added

256,000 jobs last month, compared with economists' estimate of a

rise of 160,000. The unemployment rate stood at 4.1%, compared

with expectations of 4.2%.

At 08:31 a.m. ET, Dow E-minis were down 269

points, or 0.63%, S&P 500 E-minis were down 44.25

points, or 0.74% and Nasdaq 100 E-minis were down 182.75

points, or 0.86%.
