The spike in attacks against Muslim minority in India under the ruling Hindu nationalist Bharatiya Janata Party has alarmed the human rights groups.

A Voice of America blog has highlighted the growing fear and insecurity among Muslims in India.

The blog says the uptick in hate crimes has alarmed many human rights groups, which call for decisive government measures to protect the country's minorities.

A research consultant with Human Rights Watch, Jayshree Bajoria, was quoted as saying that government has failed to prevent the growing mob attacks on religious minorities, often carried out by groups claiming to support the government.

Citing analysts, the report charged the BJP of encouraging this trend by publicly supporting attackers against minorities.
