What is understood to be a school minibus stopped with smoke billowing out of its engine this afternoon (Friday).

The minibus – thought to be carrying Portfield School students - stopped on the A477 between Neyland and Milford Haven.

Eye witnesses talked of a lot of smoke billowing across the carriageway and queues quickly building up behind.

Another coach is understood to have arrived to collect the students.

Posts on social media suggested that there were no injuries.
