During the European migrant crisis in 2015, a total of 31,145 asylum seekers crossed the Norwegian border in 2015. The number had not been as high since the Balkan wars in 1990s. Most of the asylum seekers came from Afghanistan and Syria. In 2016, the number was dramatically reduced by almost 90%. In 2016, 3460 asylum seekers came to Norway. This was partly due to the stricter border control in Europe. The EU-Turkey agreement, implemented 20 March 2016, was made in order strengthen organized channels of immigration to Europe, and prevent irregular migration from Turkey to the EU.
