More than 200 students at the University of Science and Technology in Tehran have been taken to the hospital for food poisoning at the university’s canteen since Tuesday October 15, Iranian media reported.

The students have staged a sit-in in front of the University in protest to the situation, the reports said.

A student union official told the semi-official news agency ISNA late Wednesday that the Union has called on officials to present a report on the situation within a week, “otherwise, protest gatherings will continue.” This means that the gatherings have been suspended for the time being.
