Europe's main stock markets were mostly down on Monday in the wake of more downbeat Chinese economic data and on fears of an escalation of tensions over Ukraine, analysts said.
London's FTSE 100 index of top shares managed to edge up 0.02 percent to stand at 6,558.50 points in afternoon trading.
But the Paris CAC 40 shed 0.47 percent compared with Friday's closing values to 4,314.79 points and in Frankfurt the DAX 30 declined 0.24 percent to 9,320.58 points.
"What we are still lacking is a catalyst to drive markets higher from here," said Chris Beauchamp, market analyst at IG traders.
"A simple lessening of tensions in Ukraine, or merely in-line economic data, isn't enough. Russian forces massing on the Ukrainian border are enough to provoke fears of another annexation on the fringes of Europe.

However US shares edged higher in opening trade Monday.

The broad-based S&P 500 added 0.27 percent to 1,871.48, while the tech-rich Nasdaq Composite rose 0.11 percent to 4,281.60.
