Turkey's state-run agency says a truck has slammed into a van carrying agricultural laborers in southern Turkey, killing at least 10 people and injuring four others.

Anadolu Agency says the accident occurred Friday on a highway near the town of Eregli, in Konya province.

The cause of the accident is under investigation.

It comes just four days after a bus carrying children, teachers and parents back from a school trip plunged into an irrigation canal in the southern province of Osmaniye, killing 14 people — six of them children.
