Oil rises as Middle East tensions escalate. Brent crude futures rose 21 cents to $83.67 a barrel by 11:17 GMT.
The risks of the conflict expanding in the Middle East increased after militants launched a attack on American forces in Jordan. The price of a barrel of American crude oil has increased by 8.9% since the beginning of the year. The rise in oil comes despite the faltering of the Chinese real estate market. The Chinese economy is expected to grow by less than 1% this year.
