“In the recent government meeting, I instructed the Minister of Interior and the Minister of Intelligence to investigate this issue as soon as possible and to inform our dear people of the results so that the enemy’s conspiracy to create fear and despair in the people will be thwarted,” he said.
The serial poisoning began on November 30 in the city of Qom, south of Tehran. Hundreds of students have since been hospitalized in several cities with mild poisoning.
The intoxication is said to have caused with N2 gas.
Senior authorities have urged rapid investigations aimed at identifying the perpetrators.
