Authorities in Honduras say an out-of-control tanker truck crashed into a bus on a highway outside the capital, killing at least 15 people and injuring 20.

Fire department spokesman Oscar Triminio says the death toll might rise because some passengers are still trapped in the wreckage. Triminio says the injured have been taken to University Teaching Hospital in Honduras' capital of Tegucigalpa.

Police say the truck driver fled after Sunday's crash on a highway that links the capital with southern Honduras.

Government official Lisandro Rosales says authorities are trying to determine why the truck went out of control.
