The U.N. Refugee Convention might need to be renegotiated to confront Europe's migration crisis, Danish Prime Minister Lars Løkke Rasmussen said late on Sunday.

The leader of the center-right Venstre party told TV2 television: "If this continues or gets worse... we will get to the point where we'll have to talk -- and Denmark won't be able to do it alone -- about adjusting the rules of the game."

Rasmussen said efforts should focus on refugees' rights in the first country they reach.

"If someone seeking shelter from war has lived for two or three years in Turkey, should he then go to Europe and seek asylum there? As they stand today, the rules allow people to do that, but we are going to have a discussion about that."

Denmark, which saw 18,000 requests for refugee status between January and November this year, clashed with neighboring Sweden last month when the latter indicated it would soon be unable to care for arriving asylum-seekers who may need to go back to Germany and Denmark.

“Sweden put itself in the situation it is in by carrying out extremely gentle immigration policies in every way. It’s not a solution to start guiding refugees to other countries,” Danish Integration Minister Inger Støjberg said.

In January, Danish MPs will debate a proposed law to allow the government to seize asylum-seekers’ valuables and cash to cover costs of supporting them while their claim is considered.
