But real estate firm United Development Co gained 1.8 percent after saying it sold its stake in Seef Ltd to Qatar Petroleum for 214.4 million riyals ($58.9 million).

The Saudi Arabian index was down 0.4 percent with the biggest lender, National Commercial Bank, slipping 0.9 percent and Saudi International Petrochemical Co (Sipchem) dropping 2.4 percent.

Bawan Co rose 0.8 percent after it agreed to buy its partner's stake in Arnon Plastic Industries for 191 million riyals.

In Dubai, the world's worst-performing major stock market in local currency terms last year with a 24.9 percent loss, the index inched up 0.3 percent.

Gulf Navigation Holding rose 1.2 percent after saying Tabarak Investment Group and Goldilocks Investment Co were beneficiary owners of 14.95 percent and 3.25 percent stakes in the company, under previously announced deals. The two shareholders have pledged to help develop the firm's business.
