In a statement on Wednesday, the Social Democratic Party of India described the ban on the Popular Front of India and its associate organisations as a "direct blow to democracy".
Quoting its president MK Faizy, the party alleged that whoever spoke against the "wrong and anti-people policies of the Bharatiya Janata Party regime" have faced threats of arrests and raids.
The government on Wednesday banned PFI and several of its associates for five years under a stringent anti-terror law, accusing them of having "links" with global terror groups like ISIS.
Besides PFI, the organisations which were also declared banned under the Unlawful Activities (Prevention) Act include Rehab India Foundation, Campus Front of India, All India Imams Council, National Confederation of Human Rights Organisation, National Women's Front, Junior Front, Empower India Foundation and Rehab Foundation, Kerala.
