Copenhagen - Denmark on Tuesday suspended adoptions from Nigeria, a month after the police raided a so-called "baby factory" where young girls sell their newborns to couples who are unable to conceive.
"Today I have decided to suspend all adoption from Nigeria with immediate effect," Denmark's minister for children, gender equality, integration and social affairs, Manu Sareen, wrote on Twitter.
"We must do everything we can to protect the children and to give the families peace of mind," he said in a separate statement.
Sareen said he had taken the decision after the Danish regulator, the National Social Appeals Board, said it was "no longer justifiable to adopt children from the country."
The agency said it was "difficult to ensure a lawful and ethical" adoption process, but added that couples who had already been matched with a child would not be affected by the ban.
More information was sought from the organisation that helps Danish couples adopt from Nigeria, AC International Child Support, before making a permanent decision, it said.
The police said last month they had raided a home near Lagos where eight pregnant girls were staying with plans to sell each of their newborns for nearly $2,000 (1,400 euros).
The raid brought to about 125 the number of girls the police have rescued since 2011 from "baby factories", mostly located in the southeast of the country.
The buyers are most often couples who have been unable to conceive, and baby boys typically fetch a much higher price than baby girls.
