Question:
Indigenous peoples of Mexico (Spanish: pueblos indigenas de Mexico), Native Mexicans (Spanish: nativos mexicanos), or Mexican Native Americans (Spanish: nativo america mexicanos), are those who are part of communities that trace their roots back to populations and communities that existed in what is now Mexico prior to the arrival of Europeans. According to the National Commission for the Development of Indigenous Peoples (Comision Nacional para el Desarrollo de los Pueblos Indigenas, or CDI in Spanish) and the INEGI (official census institute), in 2015, 25,694,928 people in Mexico self-identify as being indigenous of many different ethnic groups, which constitute 21.5% of Mexico's population.
The Law of Linguistic Rights of the Indigenous Languages recognizes 62 indigenous languages as "national languages" which have the same validity as Spanish in all territories where they are spoken. According to the National Institute of Statistics, Geography and Data Processing (INEGI), approximately 6.7% of the population speaks an indigenous language. That is, less than half of those identified as indigenous. 6,695,228 people 5 years or older were tallied as indigenous-language speakers in the 2010 census, an increase of about 650,000 from the 2000 census. In 2000, 6,044,547 people 5 years or older spoke an indigenous language. In previous censuses, information on the indigenous speaking population five years of age and older was obtained from the Mexican people. However, in the 2010 census, this approach was changed and the Government also began to collect data on people 3 years and older because from the age of 3, children are able to communicate verbally. With this new approach, it was determined that there were 6,913,362 people 3 years of age or more who spoke an indigenous language (218,000 children 3 and 4 four years of age fell into this category), accounting for 6.6% of the total population. The population of children aged 0 to 2 years in homes where the head of household or a spouse spoke an indigenous language was 678 954. The indigenous language speaking population has been increasing in absolute numbers for decades, but have nonetheless been falling in proportion to the national population. The recognition of indigenous languages and the protection of indigenous cultures is granted not only to the ethnic groups indigenous to modern-day Mexican territory, but also to other North American indigenous groups that migrated to Mexico from the United States in the nineteenth century and those who immigrated from Guatemala in the 1980s.

Question:
Khalid El-Masri (also Khaled El-Masri and Khaled Masri, Levantine Arabic pronunciation: ['xa:lId el'mas?ri, -'mas?re], Arabic: khld lmSry) (born June 29, 1963) is a German and Lebanese citizen who was mistakenly abducted by the Macedonian police in 2003, and handed over to the U.S. Central Intelligence Agency (CIA). While in CIA custody, he was flown to Afghanistan, where he was held at a black site and routinely interrogated, beaten, strip-searched, sodomized, and subjected to other cruel forms of inhumane and degrading treatment and torture.
At the end of 2003, El-Masri travelled from his home in Ulm to go on a short vacation in Skopje. He was detained by Macedonian border officials on December 31, 2003, because his name was identical (except for variations in Roman transliteration) to that of Khalid al-Masri, who was being sought as an alleged mentor to the al-Qaeda Hamburg cell, and because of suspicion that El-Masri's German passport was a forgery. He was held in a motel in Macedonia for over three weeks and questioned about his activities, his associates, and the mosque he attended in Ulm. The Macedonian authorities contacted the local CIA station, who in turn contacted the agency's headquarters in Langley, Virginia. According to a December 4, 2005, article in the Washington Post, CIA agents discussed whether they should remove El-Masri from Macedonia in an extraordinary rendition. The decision to do so was made by the head of the al Qaeda division of the CIA's Counter-Terrorism Center, Alfreda Frances Bikowsky, on the basis of "a hunch" that El-Masri was involved in terrorism; his name was similar to suspected terrorist Khalid al-Masri. When the Macedonian officials released El-Masri on January 23, 2004, American security officers immediately took him into custody and detained him. El-Masri later described them as members of a "black snatch team." They beat him and sedated him for transport using a rectal suppository. "The CIA stripped, hooded, shackled and sodomized el-Masri with a suppository--in CIA parlance, subjected him to "capture shock"--as Macedonian officials stood by." He was dressed in a diaper and a jumpsuit, with total sensory deprivation, and flown to Baghdad, then immediately to the "Salt Pit," a black site or covert CIA interrogation center, in Afghanistan. It also held CIA prisoners from Pakistan, Tanzania, Yemen and Saudi Arabia.
