Question: Who was sent to the country where the organization that intervened with mediation for the governments is located?

<P0-S0> the sierra leone civil war (1991 -- 2002) began on 23 march 1991 when the revolutionary united front (ruf), with support from the special forces of charles taylor's national patriotic front of liberia (npfl), intervened in sierra leone in an attempt to overthrow the joseph momoh government. <P0-S1> the resulting civil war lasted 11 years, enveloped the country, and left over 50,000 dead. <SEP> <P1-S0> A large number of international institutions have their seats in Switzerland, in part because of its policy of neutrality. <P1-S1> Geneva is the birthplace of the Red Cross and Red Crescent Movement and the Geneva Conventions and, since 2006, hosts the United Nations Human Rights Council. <P1-S2> Even though Switzerland is one of the most recent countries to have joined the United Nations, the Palace of Nations in Geneva is the second biggest centre for the United Nations after New York, and Switzerland was a founding member and home to the League of Nations. <SEP> <P2-S0> arabic dialects are the most widely spoken languages in the sahara. <P2-S1> the live in the red sea hills of southeastern egypt and eastern sudan. <P2-S2> arabic, berber and its variants now regrouped under the term amazigh (which includes the guanche language spoken by the original berber inhabitants of the canary islands) and beja languages are part of the afro-asiatic or hamito-semitic family. <P2-S3> [citation needed] unlike neighboring west africa and the central governments of the states that comprise the sahara, the french language bears little relevance to inter-personal discourse and commerce within the region, its people retaining staunch ethnic and political affiliations with tuareg and berber leaders and culture. <P2-S4> the legacy of the french colonial era administration is primarily manifested in the territorial reorganization enacted by the third and fourth republics, which engendered artificial political divisions within a hitherto isolated and porous region. <P2-S5> diplomacy with local clients was primarily conducted in arabic, which was the traditional language of bureaucratic affairs. <P2-S6> mediation of disputes and inter-agency communication was served by interpreters contracted by the french government, who, according to keenan, "documented a space of intercultural mediation," contributing much to preserving indigenous cultural identities in the region. <SEP> <P3-S0> On 5 March, Nasser's security coterie arrested thousands of participants in the uprising. <P3-S1> As a ruse to rally opposition against a return to the pre-1952 order, the RCC decreed an end to restrictions on monarchy-era parties and the Free Officers' withdrawal from politics. <P3-S2> The RCC succeeded in provoking the beneficiaries of the revolution, namely the workers, peasants, and petty bourgeois, to oppose the decrees, with one million transport workers launching a strike and thousands of peasants entering Cairo in protest in late March. <P3-S3> Naguib sought to crackdown on the protesters, but his requests were rebuffed by the heads of the security forces. <P3-S4> On 29 March, Nasser announced the decrees' revocation in response to the "impulse of the street." <P3-S5> Between April and June, hundreds of Naguib's supporters in the military were either arrested or dismissed, and Mohieddin was informally exiled to Switzerland to represent the RCC abroad. <P3-S6> King Saud of Saudi Arabia attempted to mend relations between Nasser and Naguib, but to no avail. <SEP> <P4-S0> There were several border conflicts between Colombia and Peru in the early part of the 20th century, and in 1922, their governments signed the Salomón-Lozano Treaty in an attempt to resolve them. <P4-S1> As part of this treaty, the border town of Leticia and its surrounding area was ceded from Peru to Colombia, giving Colombia access to the Amazon River. <P4-S2> On 1 September 1932, business leaders from Peruvian rubber and sugar industries who had lost land, as a result, organised an armed takeover of Leticia. <P4-S3> At first, the Peruvian government did not recognise the military takeover, but President of Peru Luis Sánchez Cerro decided to resist a Colombian re-occupation. <P4-S4> The Peruvian Army occupied Leticia, leading to an armed conflict between the two nations. <P4-S5> After months of diplomatic negotiations, the governments accepted mediation by the League of Nations, and their representatives presented their cases before the Council. <P4-S6> A provisional peace agreement, signed by both parties in May 1933, provided for the League to assume control of the disputed territory while bilateral negotiations proceeded. <P4-S7> In May 1934, a final peace agreement was signed, resulting in the return of Leticia to Colombia, a formal apology from Peru for the 1932 invasion, demilitarisation of the area around Leticia, free navigation on the Amazon and Putumayo Rivers, and a pledge of non-aggression.
