European stock index futures pointed to further sharp sell-off in equities on Friday on growing concerns that the U.S. economy could fall back into recession and on investor jitters about the health of the European financial system, according to Reuters. At 0602 GMT, futures for Euro STOXX 50 , for Germany's DAX and for France's CAC were down 0.9 to 1.2 percent. The FTSEurofirst 300 index of top European shares fell 4.8 percent on Thursday and is down 14.5 percent this month, on track to post its biggest monthly decline since at least 1997. -- SPA
