European stocks opened slightly higher Tuesday morning, as investors monitored heightened Brexit uncertainty and awaited the Federal Reserve's latest monetary policy meeting.
The pan-European Stoxx 600 was up around 0.15 percent shortly after the opening bell, with most sectors and major bourses in positive territory.
Market focus is largely attuned to central bank expectations, with the Fed due to kick-off its two-day policy meeting later in the session.
With global economic growth appearing to slow, most market participants anticipate the U.S. central bank to strike a dovish tone on Tuesday. The Federal Reserve is also expected to lower its interest rate forecasts -- or "dot plots" -- to show little or no further tightening in 2019.
