Crude oil prices rise for the first time in seven days

By Ahmad Ghaddar LONDON (Reuters) - Crude oil prices rose on Friday for the first time in seven days, but trading remains volatile less than a week before Britain goes to the polls over its EU membership. Brent crude futures were up $1.11 at $48.30 a barrel by 1142 GMT, having dropped 3.6 percent in the previous session. Analysts said that investors had closed some short positions after a week of volatile trading, which helped to bring about some correction in oil prices on Friday.
