Brent crude fell 28 cents to $114.53 a barrel ahead of the US Federal Reserve bank meeting, as investors hope for the launch of more stimulus measures due to weak economic data.

US crude also fell 31 cents at $96.23 a barrel, owing to disruptions to Gulf of Mexico production after Hurricane Isaac, reports Reuters.

Lingering geopolitical worries also affected oil prices; Israel and the US were in talks about Iran’s nuclear programme.
