Saudi calls OPEC members to stick to limits, sees oil demand up

OPEC leader Saudi Arabia said on Monday the group would quickly address weak compliance with output cuts by some OPEC states and would monitor rising production from Nigeria and Libya, which have been exempted from the curbs. OPEC has agreed with several non-OPEC producers led by Russia to cut oil output by a combined 1.8 million bpd from January 2017 until the end of March.
