Oil prices fell on Friday, weighed down by a drop in the U.S. stock market, but drew support from easing trade tensions and a temporary shutdown by Saudi Arabia of a key crude oil shipping lane.
U.S. West Texas Intermediate futures ended Friday's session down 92 cents, or 1.3 percent, at $68.69, posting a fourth straight week of declines, falling 2.5 percent.
Brent futures fell 25 cents to $74.29, but posted a 1.7-percent weekly increase, breaking a three-week losing streak.
Volume was light, with less than 361,000 U.S. crude contracts changing hands as of 1:19 p.m. EDT, compared with a 10-month daily average of about 587,000 contracts.
