A. V i s i t t o Peru 1. Background and legal and institutional framework 169. For a number of years Peru has been ridden by internal unrest, due to the activities of guerrilla movements in some parts of the country. Since 1980, the Sendero Luminoso (Shining Path) movement has conducted guerrilla warfare in the mountainous areas in the eastern part of the country, using terrorist methods to strengthen its grip on the local population. It has deployed its heaviest activities in the Province of Ayacucho. More recently, Sendero Luminoso has extended its activities to urban areas, in particular to the capital, Lima. 170. Another armed organization, the Movimiento Revolucionario Tupac Amaru (MRTA), was originally based in the urban areas, but has, since 1987, transferred its field of operations to the countryside, mainly to the Province of San Martin. 171. In a number of provinces where the guerrilla movements are active, a state of emergency has been declared (at the time of the Special Rapporteur's visit 29 provinces were under emergency law, including the metropolitan Provinces of Lima and Callao, covering about 40 per cent of the population). Under article 231 of the 1979 Constitution, the declaration of a state of emergency is restricted to a 6 0-day period, which can, however, be extended by presidential decree. Under the state of emergency, the following rights guaranteed by the Constitution may be suspended: the right to personal freedom and security, inviolability of the home, freedom of association and freedom of movement.

However, what has been suspended is the provision that no person may be arrested without warrant or may be kept in detention for more than 24 hours without such a warrant, unless he has been
