Norwegian Prime Minister Jens Stoltenberg marked the second anniversary of the terror acts that killed 77 people by calling for a continued fight against all forms of extremism.

In a wreath-laying ceremony at the government headquarters Monday, Stoltenberg said society has to stand up against “populist right-wing parties” that are on the rise in Europe, and extremist Islamists who continue to send out threats.

Far-right fanatic Anders Behring Breivik has confessed to the July 22, 2011, attacks in which he killed eight people in a bombing attack against the government headquarters and 69 others in a shooting spree at the left-wing Labor Party’s youth camp on Utoya island. A ceremony will be held at Utoya later Monday.
