Serbia's state television says a truck carrying 29 migrants has overturned, injuring many.

The report says the accident happened midday Sunday in southern Serbia. It says six people with serious injuries have been transferred to a hospital in the southern city of Nis.

Serbian police have confirmed the accident without revealing details. The state TV report says most migrants were from Afghanistan and fled the scene along with the driver.

Many migrants have been turning to smugglers to get through the Balkan countries since the traditional refugee route into Western Europe closed in March. The migrants fleeing war and poverty want to reach the wealthy nations of the European Union, but many nations have shut down their borders.

Up to 30 migrants from Africa have reached the Spanish border town of Melilla after climbing the fence that separates the European country from neighboring Morocco in North Africa.

The ones that made it all the way to the local immigrant center on Sunday chanted "Victory!" Up to 90 other migrants were unable to get over the high fence and were returned to Morocco by Spanish authorities.

Along with Ceuta, another Spanish enclave surrounded by Morocco, Melilla is often the scene of desperate migrant arrivals from regions south of the Sahara desert.

The Spanish government reinforced its border patrols in 2016, after thousands were able to reach European soil in previous years, either by swimming along the coast to the enclaves or by climbing the border fence.
