Eight opposition parties have sent a joint resolution to the BJP-led Central government, demanding the immediate release of all political detainees in Kashmir, especially the three former Chief Ministers -- Farooq and Omar Abdullah and Mehbooba Mufti. The former Chief Ministers and the political leaders have been under detention since August, when the government ended the special status of Jammu and Kashmir granted under Article 370 of the constitution and bifurcated the state into two union territories.
