A two-year-old girl found with fatal injuries in Belgium after a police chase on Thursday died from a gunshot wound to the face, prosecutors say.

The girl was in a van carrying 30 Kurdish migrants which had been pursued for an hour in southern Belgium.

The chase, which began on a motorway near the town of Namur, involved a scuffle, police said.

A police spokesman said they did not know whether the fatal shot had been fired by a police officer.

A police investigation has been launched into how the girl died, including whether there were guns in the van.

An initial report from the emergency services had stated mistakenly that the cause of death was a head injury.

"The autopsy determined the cause of death was a bullet that entered the cheek," prosecutor Frederic Bariseau told the AFP news agency.

Belgian media reported that the girl, who was with her mother, had been held out of a van window -apparently to keep the police at a distance. Local prosecutors told the BBC they could not confirm the reports.

The chase began just outside Namur in the early hours of Thursday morning.

The van drove west for several kilometres, evading police. Eventually it collided with another vehicle near Mons.

Police say the driver had jumped out to avoid being identified, and allowed the van to come to a stop itself.

It took 15 police cars and some 30 police to bring the incident to an end at around 03:00 (01:00 GMT) on Thursday. Police believe the van was linked to a people smuggling operation.

The dead girl belonged to a family housed in a migrant community at Grande-Synthe, near Dunkirk in France, French authorities said.

The 30 migrants found in the vehicle, 26 of whom are adults, are in custody and are still being interviewed.
