(Reuters) - Most stock markets in the Gulf ended higher on Tuesday as a slew of corporate earnings lifted investor sentiment, although regional tensions limited gains.
Saudi Arabia's benchmark index edged 0.1% higher, helped by a 1.4% rise in Al Rajhi Bank and a 3.1% increase in Saudi Arabian Mining Company.
Elsewhere, Mobile Telecommunications Saudi Arabia, known as Zain KSA, added 0.4% following a rise in quarterly net profit.
Separately, the kingdom's investment minister said on Tuesday the number of companies in the kingdom with a regional headquarters had reached 540, ahead of a 2030 target of 500.
In Abu Dhabi, the index closed 0.1% higher, supported by a 0.4% increase in diversified holding firm Borouge.
Dubai's main share index advanced 1%, with toll operator Salik Co rising 1.3%, and Emirates Central Cooling Systems Corp putting on 1.8%.
Oil prices - a catalyst for the Gulf's financial markets - rose more than 1%, reversing some of the previous session's 6% tumble, as a U.S. plan to buy oil for the Strategic Petroleum Reserve (SPR) provided some support, though wider concerns about weaker future demand growth exerted pressure.
The Qatari index gained 0.8%, with the Gulf's biggest lender Qatar National Bank climbing 1.1%, while petrochemical maker Industries Qatar rose 0.7% ahead of its earnings announcement.
Outside the Gulf, Egypt's blue-chip index dropped 0.5%, hit by a 1.1% fall in Commercial International Bank.
