Religious or ethnic differences have also played a role in amplifying the insurgent movements. For example, after the Soviet withdrawal from Afghanistan, many Islamic "Jihad" fighters (Mujahideen) had entered the Kashmir valley and several new militant groups with radical Islamic views emerged. Militant groups like Hizbul mujahideen and Jamaat-e-Islami asserted that struggle of Kashmir will continue till an Islamic Caliphate is achieved in Kashmir. Murder of Kashmiri Hindus, intellectuals, Liberals and activists were described necessary to get rid of un-Islamic elements. In Assam, tension exist between the native indigenous Assamese people and immigration from Bangladesh. The ULFA has attacked Hindi-speaking migrant workers. MULTA on the other hand seeks to establish an Islamic state in India via jihadist struggle of Muslims of both indigenous and migrant origin.
