Turkish police nabbed 78 migrants traveling by a passenger bus in northern Turkey's Karabük province Saturday.

The security officials pulled over a suspicious bus and found the 78 migrants in the 45-seat cramped bus.

Police said 49 of the migrants detained were Afghan nationals, 23 were Pakistani and the other six were coming from Myanmar.

The migrants were taken to a nearby sports center after going through routine procedures.

The Karabük General Directorate of Migration Management will oversee their immigration process, reports said.

Turkey is a popular route for many illegal immigrants from Middle Eastern and Asian countries. Hundreds of migrants smuggled into the country are captured every year near the borders in western Turkey, or its Aegean provinces.
