Iran has deployed mounted police in a bid to contain more than seven weeks of protests sparked by the death in custody of Mahsa Amini, according to videos posted online.The clerical state has been rocked by a protest movement that erupted when Amini, 22, died after her arrest for allegedly breaking Iran's strict hijab dress rules for women.Young women have led the way, removing and burning their head coverings, chanting anti-regime slogans and confronting security forces on the street despite a crackdown that has killed more than 300 people, according to Norway based monitoring group.Created in 2013, the mounted division of Iran's police force — known as Asvaran — has been seen on the streets of the Iranian capital in the past, mainly during parades, but it is uncommon to see it deployed during protests."Now, the public, even protesters who are not supportive of riots, demand from the judiciary and security institutions to deal with the few people who have caused disturbances in a firm, deterrent and legal manner," judiciary spokesman Masoud Setayeshi said, according to the Reuters news agency."
