June 10 (Reuters) - Gulf stock markets were mixed at the close on Wednesday after the United States and Iran exchanged fresh attacks.

Iranian media quoted the Revolutionary Guard as saying it attacked a US base in Jordan and 21 other targets in the Gulf in response to US attacks near the Strait of Hormuz.

The US military said in a post on the X platform that it bombed Iranian air defense systems, ground control stations and radar sites near the Strait after US President Donald Trump accused Iran of shooting down an Apache helicopter on Tuesday.

These clashes are among the most violent exchanges of fire since the two countries agreed to a ceasefire in April, increasing doubts about the chances of reaching a settlement to end the war that began on February 28.

The Saudi index fell 0.9 percent, affected by a 2.3 percent decline in the National Bank of Saudi Arabia, the kingdom's largest bank by assets, and a 0.4 percent drop in Saudi Aramco.

Meanwhile, Brent crude futures rose $1.74, or 1.9 percent, to $93.19 a barrel by 11:27 GMT.

The index in Dubai fell 0.5 percent, amid a 1.3 percent decline in shares of Emirates NBD Bank and a 1.4 percent drop in shares of Emaar Properties.

In Abu Dhabi, the index rose 0.2 percent.

The index in Bahrain rose 0.3 percent, and the index in Oman also advanced 0.3 percent, while the Kuwaiti index remained stable at 9176 points.

Milad Azar, market analyst at XTB Middle East and North Africa, said that GCC stock exchanges were under pressure as a result of the latest military events which have raised investor caution, but hopes of containing tensions and prioritizing diplomacy may limit the wider impact on sentiment.

The Qatari index recovered from earlier losses to close 0.1 percent higher, supported by a 0.8 percent rise in shares of Qatar National Bank, the largest lender in the Gulf region.

Outside the Gulf region, Egypt's blue-chip index fell 2.1 percent.
