Inspectors of Bosnia and Herzegovina's Service for Foreigners' Affairs earlier this week discovered a large group of illegal migrants with more than a hundred children in the area bordering Croatia.

The migrants were all transferred to reception centres in the northwestern Una-Sana Canton, where they will be given the necessary care, officials of the Service for Foreigners’ Affairs said in Sarajevo on Saturday.

The service has stepped up patrols of the area along the border with Croatia and its inspectors have found dozens of migrant families in abandoned houses in Bosanska Bojna, near the border with Croatia.

They have identified 53 families with 199 members, of whom 105 are children.

The Service for Foreigners’ Affairs has said that migrant reception centres in Una-Sana Canton have been filled to capacity and that currently, more than 3,200 migrants are staying there.

At least as many migrants are staying in two reception centres in the area of Sarajevo and the country's security ministry estimates that up to 8,000 illegal migrants are currently staying in Bosnia and Herzegovina.
