Oil prices fell on Friday after data showed that U.S. non-farm sector added fewer jobs than expected in July.
Total non-farm payroll employment increased by 162,000 in July and the unemployment rate edged down to 7.4 percent, the Labor Department said Friday.
Though July's jobless rate fell more than expected, this may be because more people have given up to seek jobs. Analysts had forecast the unemployment rate fell to 7.5 percent in July from 7. 6 percent in June.
The losses, however, were limited by concerns over disruptions in Iraq, Libya and Nigeria.
