hasty repairs to the rails, it was discovered that one of the railway tracks had been recently and deliberately severed, which caused the derailment. Later reports agreed that the crash was caused by sabotage. Thirteen months after the attack, police in Hyderabad arrested a man named Syed Abdul Nayeem, a Lashkar-e-Taiba activist, who failed a 'brainwave fingerprinting test' after being questioned by Indian police. He was charged with being involved in both this rail sabotage and a bombing which killed two people in the Sai Baba Temple. Assam After Nagaland, Assam is the most volatile state in the region. Beginning in 1979, the indigenous people of Assam demanded that the illegal immigrants who had emigrated from Bangladesh to Assam be detected and deported. The movement led by All Assam Students Union began non-violently with satyagraha, boycotts, picketing, and courting arrests. Those protesting frequently came under police action. In 1983 an election was conducted, which was opposed by the movement leaders. The election led to widespread violence. The movement finally ended after the movement leaders signed an agreement (called the Assam Accord) with the central government on 15 August 1985. Under the provisions of this accord, anyone who entered the state illegally between January 1966 and March 1971 was allowed to remain but was disenfranchised for ten years, while those who entered after 1971 faced expulsion. A November 1985 amendment to the Indian citizenship law allows non-citizens who entered Assam between 1961 and 1971 to have all the rights of citizenship except the right to vote for a period of ten years. New Delhi also gave special administration autonomy to the Bodos in the state. However, the Bodos demanded a separate Bodoland, which led to a clash between the Bengalis, the Bodos, and the Indian military resulting in hundreds of deaths. There are several organisations that advocate the independence of Assam. The most prominent of these is the United Liberation Front of Asom (ULFA). Formed in 1979, the ULFA has two main goals: the independence of Assam and the establishment of a socialist government. The ULFA has carried out several terrorist attacks in the region targeting the Indian Military and non-combatants. The group assassinates political opponents, attacks police and other security forces, blasts railroad tracks, and attacks other infrastructure facilities. The ULFA is believed to have strong links with the Nationalist Socialist Council of Nagaland (NSCN), Maoists, and the Naxalites. It
