This was reported by The Wall street Journal with reference to the US military.
According to the publication, "The Pentagon is considering the possibility of sending additional missile defense batteries, another squadron of fighter jets and additional surveillance capabilities in the Middle East to strengthen the regional presence of the military after the attack on the oil industry of Saudi Arabia last weekend."
On September 14, in Saudi Arabia, drones attacked two refineries of the state-owned company Saudi Aramco, after which fires occurred at the plants.
US Assistant Secretary of Defense Jonathan Hoffman said the United States is seriously studying the operation of Saudi Arabian air defense systems in connection with the drone attack on the kingdom’s oil facilities.
