WASHINGTON — A fire at a center for asylum-seekers in Sweden forced at least 14 people to flee for safety Tuesday in the latest suspicious blaze targeting migrant sites in a country struggling with a crush of immigrants.
The incident near Munkedal, about 200 miles southwest of Stockholm, was under investigation as possible arson, but no determination on the cause was immediately made, said a police spokesman.
The reaction from officials was swift, however, as Sweden’s tradition of accommodating asylum-seekers and others comes under pressure from anti-immigrant groups claiming the country can no longer sustain its welcoming policies.
As many as 10,000 asylum- seekers a week — many from war-scarred Syria and Iraq — have arrived in Sweden at the end of the migrant trail through Europe, which is coping with the largest mass movement of people since World War II.
‘‘A civilized and humane country like Sweden cannot accept that accommodation for asylum-seekers is set on fire,’’ wrote Swedish Foreign Minister Margot Wallstrom in a Twitter post.
On Saturday, a fire destroyed a site set to hold 80 refugees in southern Sweden.
