As per a report by BBC dated Oct 11, 2019, the Pentagon had announced the deployment of thousands of additional troops to "enhance the defence of Saudi Arabia".
US Secretary of Defence Mark Esper says he has authorised the deployment of additional forces, including fighter jets and a defence system.
He said it was in response to "threats in the region", amid efforts to protect the kingdom from "Iranian aggression".
The move comes after an attack on Saudi Arabia's oil facilities in September.
The US has increased the deployment of forces in the region by 14,000 since May, according to CNN. Saudi Crown Prince Mohammed bin Salman had requested additional support.
The deployment aims to enhance the defence of Saudi Arabia, the Pentagon says.
