The latest in the odyssey of hundreds of thousands of migrants crossing Europe in search of a new life. All times local.

10:55 a.m.

Sweden's immigration agency says it will no longer publicize the location of facilities intended to house refugees after more than 20 fires, many considered arsons, have either destroyed or made the buildings temporarily unusable.

Migrationsverket spokeswoman Johanna Uhr says future sites "will somehow be kept concealed."

Uhr says it hasn't yet decided how to do that.

In recent weeks, Sweden has seen a spate of arson attacks on asylum centers or buildings to be used as such as an influx of refugees has surged. Immigration officials estimate some 190,000 asylum-seekers will arrive this year, putting Sweden second only to Germany among EU members.

Last week, Migrationsverket called an idea by a Swedish municipality to keep a facility secret unrealistic. The agency's new position came after two more blazes early Wednesday.
