Oil prices fell Wednesday on signs that Iran was responding somewhat positively to a package of incentives by world powers hoping to curb its nuclear program.
But uncertainty over the outlook will keep a floor under oil prices, analysts said.

Light sweet crude for July delivery fell 39 cents to US$72.11 a barrel in Asian electronic trading on the New York Mercantile Exchange, mid-afternoon in Singapore.
