A key German index of investor confidence in the economy slipped in April amid concerns about the conflict in Ukraine.

The ZEW index, a survey of investment analysts, fell to 43.2 points from 46.6 the month before. Markets had expected 45.0.

The ZEW, or Centre for European Economic Research in Mannheim, said Tuesday that Ukraine "still creates uncertainty" about coming months despite strong confidence in the current state of the German economy.

The index remains well above its long-term average of 24.6 points as the German economy continues to expand with low unemployment.

Ukraine faces unrest in its eastern regions where pro-Russian activists have taken control of public buildings. Ukraine blames Russia for inciting the unrest, which is continuing the pressure on Ukraine after Russia annexed its Crimea region.
