Authorities dispersed a protest of about a thousand Azhar students who had blocked Salah Salem Road, causing a traffic conjunction, on Wednesday, a security source said. 

The source added in a statement on the interior ministry's Facebook page that traffic is now back to normal. 

Twenty four "trouble makers" were arrested in the confrontations with security forces, the statement said, adding that the necessary legal procedures are currently being taken with them. 

A Turkish man was among those who were arrested. 

Anti-Coup Students said on its Facebook that security forces and thugs attacked the students and chased them with teargas, injuring tens of them. 

Twelve Azhar students were sentenced to 17 years in prison last week on charges of raiding and vandalizing the Azhar's campus.
