The clashes followed an altercation that reportedly happened between the two groups during a ceremony organised to mark the anniversary of Operation Bluestar.
Members of the two groups, seen brandishing swords and lathis, clashed for close to half an hour.
The situation is calm now. Heavy security deployment is in place.
Terming the clashes “unfortunate,” SAD spokesperson Prem Singh Chandu Majra said the SGPC will take action against the culprits.
