The car fell on the rocky bank of the fast-flowing Vjosa River below a road that police say is frequently used by migrants from the Middle East and Africa to cross the Balkan country, police official Ardian Cipa told Reuters.

“We suspect that the driver is a citizen from Shkodra, but we are still working to identify him… We suspect that the other people killed are illegal migrants,” Cipa said.

The charred and crumpled vehicle was surrounded by at least four bodies strewn over the rocks, a Reuters witness said. Police taped off the area.

A police patrol spotted a car driving at high speed along the road in the early hours of Tuesday, but could not stop it. They later found the vehicle crashed in the ravine, Cipa said.

Last month, Albania, which is a member of NATO and aspires to join the EU, ratified a migration deal with Italy under which Rome will build migrant processing centers in the Balkan country.
