Major Gulf stock markets rose in morning trade on Tuesday, as Saudi Arabian stocks, spurred by rising oil prices, led gains.

Saudi National Bank (SNB) added 0.8% after saying it had received capital market authority approval for the merger of its unit NCB Capital with Samba Capital. SNB completed a merger with Samba Financial Group earlier this year.
