PESHAWAR, Pakistan (AP) — The head of a trade association for a large market in northwestern Pakistan says the Taliban have warned shopkeepers not to sell sex-related drugs like Viagra, or obscene films.

Shamsher Khan Afridi says he received a text message from the Pakistani Taliban on Saturday with the warning. Afridi said Monday that he distributed a pamphlet to thousands of shopkeepers in the Karkhano market in Peshawar city asking them to comply with the order.

Afridi said the Taliban's message warned that selling sex-related drugs and obscene movies was against Islam.

The Pakistani Taliban follow a hardline version of Islam and have bombed shops selling music and movies in Peshawar in the past. The group has also been waging a bloody insurgency against the government that has killed thousands.
