The US has announced plans to send forces to Saudi Arabia in the wake of attacks against the country’s oil infrastructure.
However, Defence Secretary Mark Esper insists the deployment comes at the request of The Kingdom and would be “defensive in nature”.
The BBC says total troop numbers have not yet been decided.
Yemen’s Iran-backed Houthi rebels have claimed responsibility for the attacks against two oil facilities last week.
However the US and Saudi Arabia have both blamed Iran itself.
This has led to tension.
On Friday, President Trump announced new sanctions against Iran while signalling he wanted to avoid military conflict.
The fresh sanctions will focus on Iran’s central bank and its sovereign wealth fund.
The commander of Iran’s Revolutionary Guard has since stated that the country would seek to “destroy” any aggressor.
