Ludhiana, Punjab's largest city and a major industrial hub, continued to remain tense Sunday morning as curfew continued in most parts of the city following two days of violence on Friday and Saturday in different parts.

With radical Sikh organizations led by Damdami Taksal calling for a Ludhiana bandh (shutdown) on Sunday and continuing with their dharna (protest) near Samrala crossing on the Ludhiana-Chandigarh highway, Punjab Police and para-military forces remained on high alert to maintain peace.
