In Saudi Arabia, an oil tanker anchored in the port of Jeddah was hit by a boat filled with explosives on Monday. CBS reports it was the fourth assault targeting Saudi energy infrastructure in a month. No one has taken responsibility for the attack. Last month, Houthi rebels in Yemen took credit for firing a missile at a Saudi Aramco oil company distribution station in Jeddah. This comes as the Trump administration is considering designating the Houthis as a terrorist organization despite concerns the move could worsen the humanitarian crisis in Yemen by hindering the work of aid groups.
