Europe shares close down amid Syrian tension
European shares closed sharply lower on Tuesday, amid fears of a U.S.-led military strike in response to a suspected chemical attack in Syria.
The pan-European FTSEurofirst 300 Index provisionally closed down 1.5 percent at 1,204.76 points. The Euro Stoxx 50 volatility index rose 23.8 percent to 22.17 points, its biggest daily rise since February 4.
Fears of a potential military attack against Syrian President Bashar al-Assad's regime were fueled after U.S. Defense Secretary Chuck Hagel told the BBC on Tuesday that the military is "ready to go" if President Barack Obama orders action in Syria. It came a day after U.S. Secretary of State John Kerry said all nations must stand up for accountability on the use of chemical weapons in Syria.
Meanwhile, NBC News reported that the U.S. could launch a missile strike against Syria "as early as Thursday."
All three U.S. major indices were in negative territory in early trade on Tuesday.
