European stocks closed Monday lower, as investors monitored signs of thawing tensions between the U.S. and North Korea and reacted to renewed political turmoil in Italy.
The Stoxx Europe 600 Index closed 0.32 percent lower at 389.82.
Italian stocks fell 2.07 percent at close after initially opening the session higher. This after news of a dramatic setback for the country's populist parties.
Meanwhile, Germany's DAX and France's CAC were trading slightly lower at the close. Market holidays in the U.K. and U.S. made trading slow and illiquid on Monday.
The leader of Italy's largest political party called for the country's president to be impeached after choosing to veto a choice for economy minister. Luigi Di Maio of the anti-establishment Five Star Movement said President Sergio Mattarella had prompted an "institutional crisis" by rejecting euroskeptic candidate Paolo Savona.
