The Houthi rebels in Yemen could cause further turmoil to global shipping by effectively closing the Suez Canal, experts have warned.

The terror group, backed by Iran, entered the war between Tehran and the US and Israel overnight with a missile attack towards Tel Aviv.

It is feared the militia could make a return to striking ships after attacking multiple vessels in the Red Sea during the war in Gaza.

An obvious target would be the Bab al-Mandab Strait off the coast of Yemen, a key choke point for sea traffic towards the ​Suez Canal.

Mohamad Elmasry, a professor at the Doha Institute for Graduate Studies, said today the Houthis have 'significant power'. He added:

If they decided to move to shut down Bab al-Mandeb strait, the Red Sea and, ultimately, the Suez Canal, then we would have two major choke points [closed] along with the Strait of Hormuz.

These are major international shipping waterways for international trade, so I think it can be very significant from that standpoint.

Yemen's Iran-backed Houthi rebels have entered the conflict in the Middle East and launched a missile attack on Israel.

The terror group's strike raises the prospects of a broader regional confrontation, as well as an increased threat to shipping in the region.

The group said the attack with a barrage of missiles came after continued targeting of infrastructure in Iran, Lebanon, Iraq and the Palestinian territories, adding that their operations would continue until the 'aggression' on all fronts ends.

On Friday, Brig Gen Saree, a military spokesman for the Houthis, said the rebels could join the war on behalf of Iran if attacks on the country did not cease.

'We affirm that our fingers are on the trigger for direct military intervention in any of the following cases,' Saree said.

The Pentagon is gearing up for ground operations in Iran which could last several weeks, officials revealed, as thousands of US Marines pour into the Middle East.

Defense chiefs are bracing for what insiders describe as a ‘major escalation,’ though any military action is expected to stop short of an all-out invasion, sources told The Washington Post.

Instead they will use Special Operations forces backed by infantry troops, the insiders said. It remains unclear if President Donald Trump has or will approve the Pentagon's reported plans.
