PARIS (AP) — The Latest on the migrant crisis in Europe (all times local):

Austria's interior minister says her country may reinforce controls at more border crossings if migrants seek new routes to central Europe.

Austria introduced a daily refugee cap last month, setting off a chain of border closures that shut down the Balkan route used by hundreds of thousands of migrants. Austria already had built a fence along a small part of its border with Slovenia near the Spielfeld crossing to regulate migrants' entry.

Interior Minister Johanna Mikl-Leitner told German newspaper Welt am Sonntag it would be wrong to assume "mass migration" is already over so her country is preparing to secure its border at other points.

She said that "besides Spielfeld, we are focusing on border controls at 12 other locations, optionally with fences, containers and checks by police and soldiers."

Swedish police say two blazes overnight have damaged facilities planned to be shelters for unaccompanied minors, but caused no injuries.

Police were alerted early Saturday about several small fires in a complex being renovated south of Goteborg, Sweden's second largest city. Shortly after, a fire damaged a building further south near Klippan, north of Helsingborg. The fires were quickly extinguished. No suspects have been arrested.

These were the latest suspected arson attacks on asylum centers or buildings being renovated for refugees. In recent months, Sweden has seen more than dozens such attacks as an influx of refugees has surged. The country has accepted the highest number of migrants per capita in Europe.

Several European leaders are meeting in Paris to discuss ways of strengthening Europe's stance on migration and boosting spotty growth.

France's Socialist President Francois Hollande convened other left-wing political leaders in part to discuss issues that have been pushed lower on the European agenda because of the migration crisis — such as economic reforms and rising far right sentiment. Hollande's office says they're also expected to talk about a possible British departure from the EU.

EU foreign policy chief Mogherini, EU finance commissioner Pierre Moscovici and European Parliament President Martin Schultz were expected to join the meeting.

The meeting comes as Europe is tightening up against asylum-seekers and other migrants and facing a complex summit in Brussels next week on a deal to send thousands back to Turkey.

Police detained 14 young extreme right activists after they torched tires and tried to block migrants in the French port of Calais from entering the center of town.

The group Generation Identitaire said in a statement that its activists "took control" of two bridges Saturday and wants EU and national governments to reinstate borders.

The regional police department said 14 were detained and a truck seized to show the government's "determination not to let extremist movements manipulate the migrant crisis."

Calais, long a magnet for migrants trying to sneak across the English Channel to Britain, became a flashpoint in Europe's unprecedented wave of migrant arrivals. Thousands of people escaping war and poverty in the Mideast and Africa gathered in a filthy Calais camp that authorities are gradually dismantling.
