Brent oil rose above $75 per barrel on Thursday for the first time this year as quality concerns forced the suspension of some Russian crude exports to Europe while the US prepared to tighten sanctions on Iran.
Brent crude futures were at $74.95 by 1344 GMT, up 38 cents. They earlier hit a session high of $75.60, their loftiest since October 31 last.
US West Texas Intermediate crude was at $65.85 per barrel, down 4 cents.
Poland and Germany have suspended imports of Russian crude via the Druzhba pipeline, citing poor quality. Trading sources said the Czech Republic had also halted purchases.
