Saudi Foreign Minister Adel al-Jubeir announced on Tuesday that Riyadh was contacting its allies over the measures should be taken in wake of the chemical attack in Syria’s town of Douma in the embattled Eastern Ghouta enclave over the weekend. "Our position is that those who are responsible for the use of chemical weapons must be held accountable and be brought to justice," he told reporters in Paris during a visit by the Saudi Crown Prince Mohammed bin Salman, Deputy Prime Minister and Minister of Defense. "There are consultations underway with a number of countries with regards to what steps to take to deal with this issue," he said, while not ruling out military action. The US, France and Britain have ramped up pressure on Syrias regime by pledging to take action over the use of toxic gas against civilians in Douma on Saturday, when more than 40 people may have died. Asked if Saudi Arabia would join any punitive military action against the regime, Jubeir said: "All I can say is that there are discussions on the options available to deal with this matter." US Defense Secretary Jim Mattis said Monday that Washington is working with countries "from NATO to Qatar and elsewhere", suggesting that allies are being encouraged to mount a common response. Earlier on Tuesday, US President Donald Trump and British Prime Minister Theresa May vowed to end chemical weapon attacks in Syria, drawing a red line ahead of possible military action. "The president and prime minister agreed not to allow the use of chemical weapons to continue," the White House said in a statement after a call between Trump and May.
