Iran doubts - Brent prices decline

The decline in world oil prices is associated with Iran's statements, which cast doubt on the possibility of reaching an agreement in September between the countries-producers to freeze output.

As of 8:00 MSK, the prices of October futures for Brent oil dropped 1.2%, reaching $49.34 on the ICE Exchange in London. 

The October futures for WTI oil dropped even more, by 1.4%, to $46.98 at the New York Mercantile Exchange (NYMEX).
