Iran began a military drill on Monday in the Strait of Hormuz, a critical international shipping lane and key oil export route for Gulf Arab states, which have been urging a diplomatic solution to end the long-running dispute.

Meanwhile, the U.S. military is making preparations for the possibility of weeks-long operations against Iran if President Donald Trump orders an attack, Reuters reported on Saturday, citing two U.S. officials.

The Saudi stock market extended its correction this week, trading lower as geopolitical concerns dampened sentiment, said Daniel Takieddine, co-founder and CEO of Sky Links Capital Group.
