European markets closed higher on Friday, capping off a busy week which saw investors absorb positive U.S. data and cast aside concerns about the Federal Reserve's monetary policy and heightened tensions between Russia and the West.

The FTSEurofirst 300 Index provisionally closed 0.3 percent higher at 1,309.56 points. This marked its biggest weekly gain in a month, as investors shrugged off concerns about possible military conflict in Crimea that have dominated markets over the past few weeks.
