DOHA (AFX) - US energy secretary Samuel Bodman called for more security at oil facilities around the world and said Saudi Arabia had asked Washington for help after a botched attack at a plant in the kingdom. 'It is important that we enhance the physical security of our facilities,' Bodman told reporters on the sidelines of the 10th Energy Forum in Doha. Two suicide bombers blew themselves up on Feb 24 outside the world's largest oil processing plant in Abqaiq in eastern Saudi Arabia.
