Iran's semi-official ISNA news agency is reporting that the country's authorities have detained 120 people in a private party in a coffee shop in Tehran.

The Wednesday report quotes Tehran prosecutor Abbas Jafari Dolatabadi, as saying "15 bottles of alcohol were found and 15 people were drunk and the coffee shop was closed."

Drinking is illegal under Iran's strict Islamic teachings, though there is widespread consumption of alcohol.

Dolatabadi said the 120 people were arrested on Tuesday night for attending a mixed-gender party, and that authorities also arrested two "underground singers."
