Rwanda is a constitutional republic dominated by a strong presidency. The ruling Rwandan Patriotic Front (RPF) led a coalition that included four smaller parties. In 2010 voters elected President Paul Kagame to a second seven-year term with 93 percent of the vote. Three other registered political parties participated in the elections. Elections for parliament's lower house, the Chamber of Deputies, took place in September. Candidates from the RPF and two other parties that support RPF policies won all of the open seats, and election observers reported numerous flaws, including possible irregularities in the vote tabulation process. State security forces (SSF) generally reported to civilian authorities, although there were instances in which elements of the security forces acted independently of civilian control. The most important human rights problems in the country remained the government's targeting of political opponents and human rights advocates for harassment, arrest, and abuse; disregard for the rule of law among security forces and the judiciary; restrictions on civil liberties; and support of a rebel group in the neighboring Democratic Republic of the Congo (DRC). Other major human rights problems included arbitrary or unlawful killings both inside and outside of the country, disappearances, torture, harsh conditions in prisons and detention centers, arbitrary arrest, prolonged pretrial detention, and government infringement on citizens' privacy rights. The government restricted freedoms of speech, press, assembly, and association. Security for refugees and asylum seekers improved but was at times inadequate. The government restricted and harassed local and international nongovernmental organizations (NGOs). Violence and discrimination against women and children occurred, including the recruitment by the M23 armed group of Rwandan and refugee minors as child soldiers. There was a small and declining incidence of trafficking in persons. The government restricted labor rights, and child labor continued to be a problem.
