Oil prices jumped on Monday after two large crude production bases in Libya began shutting down amid a military blockade, setting the stage for crude flows from the OPEC member to be cut to a trickle. Brent crude futures were up by 75 cents, or 1.2%, to $65.60 by 0109 GMT, having earlier reached $66.00 a barrel, the highest since Jan. 9. The West Texas Intermediate contract was up by 60 cents, or 1%, at $59.14 a barrel, after rising to $59.73, the highest since Jan. 10.
