The use of face coverings in corridors and communal areas of secondary schools is set to be introduced in Scotland.
The government is in the "final stages" of consultations with teachers and councils about having pupils wear face coverings while moving between classes.
First Minister Nicola Sturgeon said she was acting in response to new guidance from the World Health Organisation.

The use of face coverings in schools is currently voluntary, although some schools have started advising staff and pupils to wear them to help combat Covid-19.
