Oil prices rose to their highest in more than week on Monday after two large crude production bases in Libya began shutting down amid a military blockade, risking reducing crude flows from the OPEC member to a trickle.
Brent crude was up 37 cents, or 0.6%, at $65.22 by 0952 GMT, having earlier touched $66 a barrel, the highest since Jan. 9.
The West Texas Intermediate contract was 24 cents, or 0.4%, higher at $58.78 a barrel, after rising to $59.73, the highest since Jan. 10.
