Up to 40 schools have been closed in a town in central Ghana and a large number of government workers have fled following a threat to attack people from outside the town.
An unidentified group known as the Concerned Members of Banda Ahenkro made the threat, which said that non-locals would be targeted in the way foreigners were in South Africa.
The complaint is that Ghanaians from outside the town have taken jobs that locals should have.
About 70% of public sector workers including teachers and health personnel have fled.
Police have been deployed to prevent violence and the traditional authorities in Banda Ahenkro have assured government that they will do everything possible to maintain peace in the area.
