Oil prices rose half a percent on Friday and were headed for their biggest weekly increase since mid-July as renewed hostilities between the US and Iran intensified concerns over potential disruptions to oil supplies from the Middle East.
The latest US attacks, which killed and wounded dozens of people, including Iranian civilians, have resulted in the most intense clashes between the two countries since July. The conflict, which began with US-Israeli strikes at the end of February, has now entered its seventh month.
