PARIS, June 3 (Reuters) - European stocks extended their losses on Friday as lower-than-expected U.S. monthly jobs data fanned worries over the outlook for the world's biggest economy, particularly hitting cyclical sectors such as mining.
At 1306 GMT, the FTSEurofirst 300 <.FTEU3> index of top European shares was down 1 percent at 1,104.69 points, a level not seen since late March. The index, which has lost 2.7 percent so far this week, is poised to record a fourth consecutive weekly loss.
"It was a very disappointing number. It seems to be in line with the overall deterioration in the U.S. macro fundamentals. Therefore, it should be negative for the equity market," said Paresh Upadhyaya, senior strategist at Bank of America-Merrill Lynch in New York.
The euro zone's blue chip Euro STOXX 50 <.STOXX50E> index was down 0.8 percent at 2,761.81 points, hitting a near three-month low and breaking below a 12-month upward trendline, sending a bearish signal.

The Euro STOXX 50 volatility index <.V2TX>, one of Europe's main fear gauges, rose nearly 5 percent to a one-week high, signalling a rise in investor aversion for risk.
