Following a Boko Haram suicide bombing in its capital, Chad has warned that anyone found wearing the Muslim full-face veil would be arrested.

The suicide attack in a bustling N’Djamena market was carried out by a man disguised as a woman in a full-face veil.

“This attack just confirms that a ban” on the full-face veil was justified, national police spokesman Paul Manga said, adding that “it now must be respected more than ever by the entire population.”

“Anyone who does not obey the law will be automatically arrested and brought to justice,” he warned.

The bomber detonated his explosives belt when he was stopped for security checks at the entrance to the city’s main market.

Despite being a Muslim majority nation, Chad banned the full-face veil and ramped up security measures. Also, the nation bombed militant positions in Nigeria.

Boko Haram claimed responsibility on Twitter for the suicide bombing, signing off as “Islamic State, West Africa province” — the militants’ self-styled moniker since pledging allegiance to the Islamic State group in March.

Boko Haram’s deadly insurgency has killed at least 15,000 people since 2009 and left more than 1.5 million homeless.

A four-nation coalition of Nigeria, Niger, Chad and Cameroon has reportedly pushed out the militants from captured towns and villages in an operation that began in February.
