European shares fell for a fifth straight session to a new three-month low, led down by commodities stocks, with investors becoming jittery before the US Federal Reserve's policy meeting and next week's EU referendum in Britain.

    The pan-European FTSEurofirst 300 index dropped 1% to its lowest level since late February, while the broader STOXX Europe 600 index also fell 1.1%. European basic resources and oil and gas indexes fell 2.4% and 1.5% respectively, tracking weaker commodities prices. 

    Uncertainty over this week's two-day Fed meeting, starting later in the day, also weighed on markets, though the US central bank is widely expected to leave rates unchanged after the much weaker-than-expected May nonfarm payrolls report.
