Amid an intensifying crackdown on nongovernmental groups that receive foreign funding, Indian activists are accusing the government of stifling their right to dissent in the world's largest democracy.

India has tightened the rules on nongovernmental organizations over the past two years, following protests that delayed several important industrial projects. About a dozen NGOs that the government said engaged in activities that harm the public interest have seen their permission to receive foreign donations revoked, as have nearly 4,000 small NGOs for what officials said was inadequate compliance with reporting requirements.

The government stepped up its campaign this month, suspending the permission that Indian Social Action Forum (INSAF), a network of more than 700 NGOs across India, had to receive foreign funds. Groups in the network campaign for indigenous peoples' rights over their mineral-rich land and against nuclear energy, human rights violations and religious fundamentalism; nearly 90 percent of the network's funding comes from overseas.
