Iran condemns US 'deceit' over Saudi oil attacks
Iran has accused the US of "deceit" after Secretary of State Mike Pompeo said Tehran was behind damaging drone attacks on two Saudi oil facilities.
Mr Pompeo had rejected claims by Yemen's Iran-backed Houthi rebels that they had carried out the attacks.
Iran's Foreign Minister Javad Zarif said that "blaming Iran won't end the disaster" in Yemen.
Saudi Arabia said Saturday's strikes had halved its crude oil production to 5.7 million barrels a day, BBC reports.
All eyes will be on the markets when they reopen on Monday, with experts expecting a significant rise in price.
Since ousting Yemen's president in 2015, the Houthis have been fighting a Saudi-led and Western-backed coalition.
They said they had deployed 10 drones to attack the Abqaiq processing plant and the Khurais oilfield early on Saturday.
But Mr Pompeo said there was "no evidence" the drones came from Yemen and instead accused Iran.
The US has blamed Iran for other attacks on oil supplies in the region this year, amid continuing tension following President Donald Trump's decision to reinstate sanctions after abandoning the landmark international deal which limited Tehran's nuclear activities.
