ATHENS (Reuters) - A bus driver shuttling pupils to school in northern Greece shocked their parents when he put on a porn tape, say officials.

The incident on Tuesday in the town of Kilkis prompted dozens of complaints by parents who have asked the bus company to sack him.

"The driver said 'kids we've got porn, do you want to watch it'," one of the pupils told reporters on Thursday. "Everyone started shouting yes, yes and he just put in a tape and we watched it on the small TV screens on the bus."
