Attacks on two Saudi oil refineries: what followed

Tensions in the Middle East have surged following attacks on two major oil facilities in Saudi Arabia. The pre-dawn attacks on September 14 knocked out more than half of the top global exporter's output - five percent of the global oil supply - or about 5.7 million barrels per day.

Yemen's Houthi rebels claimed responsibility but US Secretary of State Mike Pompeo swiftly accused Iran, which rejected the allegations. Saudi Arabia, meanwhile, promised to "confront and deal with this terrorist agggression", while US President Donald Trump hinted at possible military action.

Turkish President Recep Tayyip Erdogan vowed Ankara would continue to purchase oil and natural gas from Iran despite US sanctions.
Saudi Foreign Minister Ibrahim al-Assaf, called on the UN and the world to apply "utmost pressure with every tool available" to end what he said was Iran's aggressive conduct. At UNGA on Thursday, the foreign minister again blamed Iran for the September 14 missile and drone attack on Saudi Arabia's oil facilities and said the best way to control Tehran was by cutting off its financial resources.
Al Jazeera's Rosiland Jordan noted that when a country was looking for international support after such an attack it would normally call for an emergency meeting of the Security Council. "There's been no such request from the Saudi government,'' he said.

The Pentagon said it plans to send four radar systems, a battery of Patriot missiles, and about 200 support personnel to bolster Saudi Arabia's defences after the largest-ever attack on the kingdom's oil facilities this month.
The deployment details clarify the Pentagon's announcement last week about US plans to deploy more forces to Saudi Arabia after the September 14 attack on the world's biggest crude oil processing facility, which Washington has blamed on Iran.
In a statement, the US military said it was also putting additional capabilities on "prepare to deploy orders" - meaning they could be mobilised more quickly in a crisis. These include two additional Patriot missile batteries and a Terminal High Altitude Area Defense system, or THAAD.
Iranian President Hassan Rouhani challenged countries who accused Iran of carrying out this month's attack on a Saudi Arabian oil facility to provide evidence.
"Those who make the allegations must provide the needed proof. What is your evidence?" he told reporters in New York, a day after addressing the UN General Assembly.
The United States, France, Germany and Britain have all blamed Iran for the attacks on the kingdom's Abqaiq plant and the Khurais oil field, which knocked out half of Saudi Arabia's oil production.
Rouhani also urged the US to "cease this policy of maximum pressure" in favour of "dialogue, and logic and reason".
