NEW YORK, July 21 (Reuters) - U.S. crude oil futures rose for a third day on Thursday to close at a four-week high above $99 a barrel as mid-Atlantic region manufacturing rebounded in July, outweighing higher jobless claims last week.
Signs of progress in achieving agreement to bail out debt-strapped Greece and a possible deal to avert a default in U.S. debt as well as confirmation that the International Energy Agency would not release more emergency oil for now also lifted buying sentiment.
