Brent crude slipped ten cents to $104.28 a barrel as investors anticipated more US stimulus measures to support growth, while investors feared that tensions in the Middle East could affect oil supply further.

US crude fell 30 cents at $88.67 as single-family home sales in June showed the biggest decline in more than a year, while crude oil inventories rose by 2.72 million barrels last week.

Fears of a chemical warfare by Syria against the 16-month revolt against President Bashar al-Assad also added to supply concerns, reports Reuters.
