LONDON—Oil prices rose on Monday as Iranian nuclear talks appeared to hit obstacles and an embargo on Russian oil shipments loomed, with tight supply struggling to meet still robust demand.
Brent crude futures rose 88 cents, or 1 percent, to $93.72 a barrel by 1100 GMT. U.S. West Texas Intermediate crude was up 69 cents, or 0.8 percent, at $87.48.
