Why are some schools closing, and what does it mean?

The Department of Education says that any school building with RAAC - which is a certain type of concrete - "should no longer be open".

Because of this, over 100 schools across the country have been told to shut their buildings, just a few days before the start of the school year.

The government says closed buildings can't open up again until safety measures, like repairs to strengthen the building, have been put in place.
