A police chief in norther Iran has threatened to “break the neck” of anyone who speaks out against compulsory hijab, adding that he will take responsibility for that.

Hassan Mafkhami police commander in Mazandaran province on the shores of the Caspian Sea was inspecting beaches where millions of Iranians visit from the capital Tehran and other cities during the summer. Women are forbidden to bathe without cloths and should be fully cladded on the beaches.

He told law enforcement agents, “In this province and its towns if someone God forbid raises her voice, break her neck according to law and I will take responsibility for it.”

Tens of thousands of Iranian women have been defying compulsory hijab this year after nationwide protests erupted last September when Mahsa Amini, a 22-year-old woman died in ‘morality police’ custody from severe head injuries.

Hardliners in the clerical-military regime, however, have vowed “to restore order”, saying that hijab for women is their “red line”. The conservative dominated parliament is debating a bill to further codify the hijab, including imposing hefty fines on women and denial of social services if they refuse to cover their heads.

The issue has turned into a rallying cry against the regime that regularly intervenes in the private lives of the citizens. Many regime insiders have urged caution, saying that another hijab incident can lead to renewed anti-government protests.

Police officials have vowed to install “smart cameras” on the beaches of the Caspian Sea to identify women who break the rules.
