Saudi Aramco evacuated its headquarters in Dhahran on Thursday and asked employees to work from home, according to sources familiar with the matter. People familiar with the matter said the move was taken after the headquarters sounded an alarm. People familiar with the matter declined to be named due to discussions on security matters. They said the reason for the alert was unclear, and it was not clear how long employees would need to work from home. Neither Saudi Aramco nor the Saudi Ministry of Energy immediately responded to requests for comment. Last week, a tower in the headquarters park of the world's largest oil export company was attacked by the Houthis in Yemen, causing damage to three floors and causing a fire. In recent weeks, the Houthis have intensified their attacks on Saudi Arabia, frequently attacking airports and energy infrastructure.
