From harassing activists...

During the period between June 2016 and June 2017, Amnesty International found that at least 169 critics or their relatives were arrested, summoned, interrogated, prosecuted, imprisoned, banned from travel or threatened. Human rights defenders, lawyers, journalists, political activists and leaders, Shi’a clerics, and peaceful protesters have been particularly impacted.

Security forces, including the National Security Agency (NSA), have increasingly used excessive force, beating peaceful protesters, firing shotguns and semi-automatic rifles, and firing tear gas from armoured personnel vehicles or helicopters into houses or directly at protesters. Since the beginning of 2017, security forces have killed six people, including one child, and injured hundreds.
