Authorities in Ladakh have tightened security after the arrest of renowned environmental activist and educator Sonam Wangchuk under India’s National Security Act. Wangchuk, who was leading a hunger strike demanding full statehood for Ladakh, was detained on Friday. Heavy security measures were imposed across Leh and adjoining areas this morning. The protest movement, largely led by the youth, has drawn comparisons to political uprisings in Sri Lanka, Bangladesh, and Nepal. Tensions escalated last Wednesday when clashes left four people dead and at least 50 injured.
