The top official in the north Indian state of Punjab has convened an emergency meeting to attempt to defuse days of violent protests set off by the desecration of a Sikh holy book.

On Tuesday, hundreds of Sikh protesters again blocked the state's main roads and highways, demanding action be taken against whoever tore 20 pages from a copy of the book, the Guru Granth Sahib, at a Sikh temple.

Police have arrested three people in connection with the desecration.

Opposition leaders have accused the government of not doing enough to investigate the incident. Anger spiked in the state soon after the desecration when police fired into a crowd of protesters, killing two men.

The daily highway blockades have led to traffic chaos and disrupted business.
