The pan-European Stoxx 600 was down 0.9% at 491 at midday, with all major regional bourses in the red. US markets were lower overnight while Asian shares were mixed.
"Despite assurances from US Fed officials that the world's largest economy is not headed for a recession, stocks wilted under pressure amid concerns about the outlook for the US economy," said Patrick Munnelly of Tickmill Group.
"As a result, Asian stock markets are trading mostly lower on Thursday, following the generally weak handover from Wall Street overnight. In addition, increased geopolitical tensions are negatively impacting the markets."
