On February 14, 2015, 22-year-old Omar Abdel Hamid El-Hussein fired a gun at an event in the Krudttonden cultural centre in Copenhagen, killing one person. The following day he shot another person at a synagogue.
The shootings came a month after the attack on the French satirical magazine Charlie Hebdo, in which brothers Chérif and Saïd Kouachi killed 12 people.
In the aftershock of these attacks, European countries announced new security measures and increased intelligence cooperation with countries in the Middle East.
