A row has been brewing for months in the southern Indian state of Karnataka after dozens of Muslim students were barred by authorities from entering colleges because they were wearing the hijab. 

Widespread protests and counter protests by students attending local colleges and pre-universities have erupted across the southern coastal state, raising tensions in the communally sensitive region.

Female Muslim students have lobbied for days outside the gates of their colleges, demanding the administration let them attend classes wearing the hijab. 

Their protests have been met by counter-demonstrations by students linked to right-wing Hindu groups. They wear saffron scarves - a colour used by hardline nationalists - and march in the streets chanting "Jai Shri Ram", a traditional Hindu salutation that has in recent years become a war cry.

In this week's Beyond the Headlines, Nilanjana Gupta looks at why the hijab is the source of more division than ever in India.
