NEW DELHI — Thousands of supporters of India's youth-led "cockroach" movement have been camping in the capital New Delhi to demand the resignation of Education Minister Dharmendra Pradhan, in the biggest public challenge to Prime Minister Narendra Modi in his third term.

The movement gained momentum following leaks of high-stakes exams and drew wider attention after police forcibly moved hunger-striking activist Sonam Wangchuk.

The months-old movement is seen as the biggest public challenge to Prime Minister Narendra Modi in his third term in office.
