European shares fell for the fourth-straight session on Monday as investors worried about the impact of increasing Ukraine-Russia tensions and of central banks’ resolve to tame inflation on economic growth and corporate profits.

The region-wide STOXX 600 index was down 0.6% by 0708 GMT, hitting its lowest level since Oct. 3.

The index has fallen more than 3% in four sessions on worries that major global central banks, especially the US Federal Reserve, will continue to raise interest rates aggressively to tame inflation.
