The Integration Ministry of Denmark announced that the Danish government on Wednesday decided to extend the temporary border control on the country's southern border with Germany by 20 more days.
"The assessment is that there is still a risk that a large number of illegal immigrants accumulate in Denmark," the ministry said.
Previously, the Danish government put a 10 day border control into effect, as a similar action was previously taken by Sweden.
Europe is facing the biggest refugee influx into the continent since World War II.
The International Organisation for Migration announced last December that one million refugees fleeing war and poverty in the Middle East and Africa crossed into Europe in 2015, while nearly 3,700 people lost their lives in their attempt.
