The most egregious human rights problems stemmed from the state's widespread disregard for the well-being of a majority of its citizens. This manifested itself in a complete denial of citizens' ability to change their government, a breakdown in law enforcement's ability to protect the majority of citizens from state and nonstate violence, and the reported indiscriminate use of violence against civilians and civilian institutions. The government arbitrarily and unlawfully killed, tortured, and detained persons on a wide scale. Government forces reportedly conducted attacks on civilians in hospitals, residential areas, schools, and camps holding internally displaced persons (IDPs); these attacks included bombardment with improvised explosive devices, commonly referred to as "barrel bombs" (containing a combination of jet fuel and TNT, usually dropped by a helicopter). The government reportedly continued the use of torture and rape, including of children. It reportedly used the massacre of civilians, as well as their forced displacement, rape, and starvation, as military tactics. Government authorities rigorously denied citizens the ability to exercise civil liberties and freedoms of expression, movement, peaceful assembly and association, and the right to a fair public trial. Government authorities reportedly detained without access to fair trial tens of thousands of individuals including those associated with nongovernmental organizations (NGOs), human rights activists, journalists, humanitarian aid providers, religious figures, and physicians.Other continuing human rights problems included: restrictions on religious observance and movement; abuse of refugees and stateless persons; prevention of NGOs and individual activists, especially those working on civil society and democracy matters, from organizing; restrictions on access for medical providers to persons in critical need; rampant governmental corruption; violence and societal discrimination against women and minorities; and restrictions on workers' rights.Impunity was pervasive and deeply embedded in the security forces and elsewhere in the government, since the government did not attempt to investigate, punish, arrest, or prosecute officials who violated human rights. The government often sheltered and encouraged those in its ranks to commit abuses.
