Indian police have detained hundreds who defied a ban on protests against a controversial new citizenship law.

The ban has been imposed in parts of the capital Delhi, and throughout the states of Uttar Pradesh and Karnataka.

Internet services are suspended in some parts of Delhi close to protest sites. There have been days of demonstrations across India, some violent.

The new law offers citizenship to non-Muslim illegal immigrants from Pakistan, Bangladesh and Afghanistan.

Among those detained are Ramachandra Guha, a prominent historian and outspoken critic of the government, in the southern city of Bangalore; and political activist in Yogendra Yadav in Delhi.
