M Saleem Pandit | TNN Srinagar: The Congress-led government in J&K was on the brink of collapse on Saturday after PDP leader Mehbooba Mufti marched to governor N N Vohra's office in Srinagar and handed in a letter withdrawing support to the government. The move came amidst spiralling violence over the decision to build facilities for Amarnath pilgrims near Sonmarg and Pahalgam and transfer of land to the shrine board. The PDP and separatistbacked protests have led to mobs taking over streets in Muslim-majority areas, attacking yatris.
