Dozens of U.S. citizens working for foreign oil companies in the Iraqi oil city of Basra were preparing to leave the country on Friday, company sources told Reuters.
The U.S. embassy in Baghdad urged all citizens to depart Iraq immediately, hours after the U.S. killed Iranian Quds Force leader Qassem Soleimani and Iraqi militia commander Abu Mahdi al-Muhandis in an air strike.
The evacuation will not affect operations, production or exports, Iraqi oil officials said.
