Slovenia's authorities stated on Tuesday that in the first eight months of this year there were 9,801 illegal border crossings by migrants as against 5,899 cases in the corresponding period of 2018.
In August alone, 2,352 irregular migrants were registered.
The Interior Ministry said that the August figures bore witness to the fact that illegal migration is still on the rise even though it is not as great as it was at the time of the 2015 and 2016 migrant crisis.
The largest number of irregular migrants came from Pakistan (2,344), Afghanistan (1,064) and Morocco (759).
The Slovenian ministry says that 2,577 migrants sought asylum in the first eight months of this year as against 2,098 in the corresponding period of 2018.
Under the readmission agreement between Slovenia and Croatia, from January to August this year, 6,477 migrants were sent back to Croatia as against 2,330 last year.
