Question: Who helped to rebuild society after 70% of the Tutsi population were killed?

Context paragraphs:
United States Ambassador to Burundi: The part of Africa that is now Burundi and Rwanda was a feudal monarchy headed by a "mwami" (king) and a "ganwa", a feudal hierarchy of Tutsi nobles and gentry until 1890.  In that year the Germans attacked the nation and attempted to subdue it with armed force.  Eventually the Germans backed an attempted "coup d’état" against the king, Mwezi Gisanbo.  The "coup" was unsuccessful, but Gisabo was eventually forced to concede and agreed to German suzerainty.  The Germans then helped him suppress the revolt.  Thus Burundi became part of German East Africa in 1890.

Gacaca court: The Gacaca court (] ) is a system of community justice inspired by Rwandan tradition where "gacaca" can be loosely translated to "justice amongst the grass".  This traditional, communal justice was adapted in 2001 to fit the needs of Rwanda in the wake of the 1994 Rwandan Genocide (also known as "Hutu vs Tutsi" ) where an estimated 800,000 people were killed, tortured and raped.  After the genocide, the new Rwandan Patriotic Front's government struggled to pursue justice on such a massive scale, and therein to develop just means for the humane detention and prosecution of the more than 100,000 people accused of genocide, war crimes, and related crimes against humanity.  By 2000, approximately 130,000 alleged genocide perpetrators populated Rwanda's prisons (Reyntjens & Vandeginste 2005, 110).  Using the justice system Rwanda had in place, the trial of such massive numbers of alleged perpetrators would take well over 100 years during which Rwanda's economy would crumble as a massive amount of their population awaited trial in prison.  For this reason they chose to adapt and create a large-scale justice system, which would work alongside the International Criminal Tribunal for Rwanda, in order to heal as a people and to thrive as a country.

Grégoire Ndahimana: Grégoire Ndahimana (born 1952) is the former mayor of Kivumu, Rwanda.  Indicted and arrested for alleged war crimes by the International Criminal Tribunal for Rwanda (ICTR), Ndahimana is thought to be one of the key figures in the 1994 Rwandan Genocide, and is claimed to have had up to 6,000 Tutsi killed.  He will stand trial in Arusha, Tanzania, where the ICTR currently holds its courts.

Kiremba: Kiremba is a small town in the Commune of Bururi in Bururi Province in southern Burundi.  By road it is located 7 kilometres southeast of Bururi and 4.3 kilometres northwest of Buta.  On April 30, 1997, the same day as the massacre at nearby Buta, the FDD killed Hutu and two Tutsi people in Kiremba, burning the local hospital and raping two women before killing them.  In 2004, the people were tested for epilepsy.

1965 Burundian coup d'état attempt: On 18–19 October 1965, a group of ethnic Hutu officers from the Burundian military attempted to overthrow Burundi's government in a coup d'état.  The rebels were angry about the apparent favouring of ethnic Tutsi minority by Burundi's monarchy after a period of escalating ethnic tension following national independence from Belgium in 1962.  Although the Prime Minister was shot and wounded, the coup failed and soon provoked a backlash against Hutu in which thousands of people, including the participants in the coup, were killed.  The coup also facilitated a militant Tutsi backlash against the moderate Tutsi monarchy resulting in two further coups which culminated in the abolition of Burundi's historic monarchy in November 1966 and the rise of Michel Micombero as dictator.

Buta, Burundi: Buta is a small town in the Commune of Bururi in Bururi Province in southern Burundi.  It is located 106 km by road southeast of Bujumbura and 11.3 km by R.N.16 and R.N.17 southeast of Bururi.  A ten-minute drive from Bururi, Buta is an important garrison town.  On April 30, 1997, 44 Hutu and Tutsi seminarians were slaughtered at the minor seminary in Buta, most of whom were "Catholics of African origin: 8 from Rwanda, 6 from Congo, and 1 from Nigeria as well as the 4 from Burundi."  36 killed were seminary students and 8 killed were staff.

Rwandan genocide: The Rwandan genocide, also known as the genocide against the Tutsi, was a genocidal mass slaughter of Tutsi in Rwanda by members of the Hutu majority government.  An estimated 500,000–1,000,000 Rwandans were killed during the 100-day period from April 7 to mid-July 1994, constituting as many as 70% of the Tutsi population.  Additionally, 30% of the Pygmy Batwa were killed.  The genocide and widespread slaughter of Rwandans ended when the Tutsi-backed and heavily armed Rwandan Patriotic Front (RPF) led by Paul Kagame took control of the country.  An estimated 2,000,000 Rwandans, mostly Hutus, were displaced and became refugees.

Pro-Femmes Twese Hamwe: Pro-Femmes Twese Hamwe is a national women's organization in Rwanda founded in 1992 that is recognized internationally for its contributions to rebuilding society after the 1994 Rwandan genocide.  These women took on the role of reconstructing what had been damaged.  In order to restore Rwanda the women created projects to improve the economy, establish peace, and offer new opportunities.  The 13 women that started this organization were determined to speak out for injustices, especially against women, so they became a voice for change.  The genocide incident caused great destruction; however, since 1994 the organization has grown to include 58 member associations.  These women work hard to make the changes and help the minorities grow and develop.

Paul Rusesabagina: Paul Rusesabagina (] ; born 15 June 1954) is a Rwandan humanitarian who, while working as a concierge at the Hôtel des Mille Collines in Kigali, hid and protected 1,268 Hutu and Tutsi refugees from the Interahamwe militia during the Rwandan Genocide.  None of those refugees were hurt or killed during the attacks.

LMS Rebuilt Royal Scot Class: The London Midland and Scottish Railway (LMS) Rebuilt Royal Scot Class is a class of 4-6-0 steam locomotives.  70 members of this class were rebuilt by the LMS and its successor British Railways (BR) from LMS Royal Scot Class engines by the replacement of their life expired parallel boilers with a type 2A boiler over the period 1943-1955.  (The class sometimes is numbered 71 as it included a prototype 1935 rebuild LMS (4)6170 British Legion, but sufficient technical differences existed which dictate that it is treated separately).  They were the second type of LMS 2 and 2A boilered 4-6-0 locomotives, after the rebuild of "British Legion" and the LMS Rebuilt Jubilee Class.
