    Benchmark indexes in mainland China and Hong Kong struggled amid ongoing tensions in the Middle East.

    The Hang Seng Index increased 0.5%, and the mainland-focused CSI 300 Index declined 0.3% after the U.S. carried out air attacks targeting locations in southern Iran. 

    The Brent crude oil prices rose 1% to $98.35 a barrel following the latest US attacks, undermining the prospects of a near-term peace deal between the US and Iran. 

    Crude oil prices regained the upward momentum as the shipments through the Strait of Hormuz remained disrupted for the eighth week under the dual blockade.
