Slovenia's government has cleared the way for the armed forces to assist police in managing the influx of migrants from Croatia.

Officials said Saturday the military will be deployed if there is a large number of migrants or illegal crossings. Authorities say the army would provide logistical support to the police, but won't have any authority over migrants.

Prime Minister Miro Cerar says "we are going to focus even more on safety and security and order so our country can function normally." He adds that Slovenia is a transit country for migrants and if "destination countries begin adopting stricter measures at the border, Slovenia will follow suit."

Most migrants want to go to the rich EU countries. Slovenia says it will allow in new groups after previous groups leave the country.

A disused school in southern Sweden that was planned to house 80 refugees has burned to the ground in what police say is a case of "aggravated arson."

No arrests have been made.

Ljungby town officials said the school in Kanna had been destroyed. It closed in 2011and had received a make-over to be ready to house refugees.

Earlier this month, Sweden's government has ordered the immigration agency to set up tents to provide temporary accommodation and has tasked local authorities with drawing up an inventory of all premises that can be used as shelters.

More than 150,000 asylum seekers are expected to arrive in Sweden this year.

Slovenia's official STA news agency says some of the migrants who have entered the country from Croatia have already reached the border with neighboring Austria.

The report says several dozen migrants were being registered by Austria's authorities at the Spielfeld crossing and then would be taken further inland.

Slovenia has set up a refugee center at the border with Austria as most migrants fleeing war and poverty in the Middle East, Africa or Asia wish to reach Germany or other rich EU nations.

Migrants were rerouted to Slovenia from Croatia on Saturday after Hungary closed its border for free flow of people wishing to go to Western Europe.

Several hundred people have entered Slovenia so far on Saturday and more are expected later in the day.
