Indian police say a man has confessed his involvement in bombings near a rally by opposition leader Narendra Modi and said the attacks were ordered by an outlawed Islamic group.

The six blasts in Bihar's capital of Patna killed six people and injured 83 on Sunday.

Police official Manu Maharaj says one of five men being questioned said the bombings had been ordered by the Indian Mujahideen, which has been linked to the banned Pakistan-based Islamist rebel group Lashkar-e-Taiba.

No group has yet claimed responsibility for Sunday's blasts.

Modi's Hindu nationalist Bharatiya Janata Party hopes to unseat Prime Minister Manmohan Singh's Congress-led coalition in next year's elections. Critics worry Modi's rise could exacerbate sectarian tensions between India's majority Hindus and its 138 million Muslims.
