Fresh violence broke out in Kashmir as a 26-member team of Indian parliamentarians arrived in Srinagar on Sunday to allay tensions in the restive state.
The conciliatory effort received another blow as Hurriyat, a group fighting for Kashmir's freedom, declined the offer to meet the delegation.
The Hurriyat rejected Mufti's invitation for lack of clarity in the engagement process.
Violence erupted in Shopian district in Kashmir on Sunday morning, injuring at least 50 people.
A group of protesters also set ablaze the office of district magistrate (a senior government official), national radio broadcaster All India Radio tweeted.
The clash broke out after Indian security forces tried to intervene a pro-freedom rally in Pinjura village.
The clashes coincide with the arrival of Indian lawmakers in the Valley. The delegate, headed by India's home minister Rajnath Singh, is on a two-day visit to Srinagar to discuss the security situation in the Valley.
The delegate met Jammu and Kashmir chief minister Mehbooba Mufti earlier in the day to discuss ways to tackle the festering problem in the state.
"We intend to talk to individuals and groups who want peace and normalcy in Kashmir valley," India's home minister had said before leaving for Kashmir.
Singh said the Centre would take a final decision with regard to Kashmir unrest on the basis of feedback and suggestions given by the delegation, which comprises members cutting across political affiliation.
Jammu and Kashmir chief minister Mufti yesterday invited leaders of Hurriyat for talks with the all-party delegation. Hurriyat is an organisation that is fighting for Kashmir's independence.
Kashmir has been gripped with tension following the killing of Hizbul Mujahideen commander Burhan Wani on July 8.
