Suspicious materials seized by the Moroccan authorities during the arrest of 10 suspected terrorists last month contained biological weapons, the Interior Ministry in Rabat said on Thursday.
The suspected terrorist cell, which is said to be linked to the Islamic State extremist group, was planning to use the hazardous materials in terrorist attacks in the country, the ministry said.
According to the statement, the materials can destroy the human nervous system and eventually cause death. They could also lead to environmental hazards if leaked through water or air.
On February 18, security forces had apprehended 10 terrorist suspects, including a French national, in the Atlantic port city of al-Jadida, located some 150 kilometres south of the capital Rabat.
