A total of 34,131 migrants had entered Slovenia since Saturday, when the influx began, compared with 21,455 the previous day, an increase of 12,676.

On September 23, Hungary, which has since closed its borders, counted a record 10,046 arrivals in one day.

European Commissioner for Migration and Home Affairs Dimitris Avramopoulos on Thursday will visit Slovenia to discuss the migrant crisis, while Commission President Jean-Claude Juncker called an extraordinary meeting of several European leaders for October 25.

Juncker invited the leaders of Austria, Bulgaria, Croatia, the former Yugoslav Republic of Macedonia, Germany, Greece, Hungary, Romania, Serbia and Slovenia.

Slovenia's parliament has given more power to the army which is helping police control the border, while the country also plans to rehire retired police to help.
