Curfew was imposed on Sunday in Sopore town in north Kashmir that witnessed massive protests after two youths were killed and another was wounded in a firing incident even as a case was registered against the army in this regard.

"Curfew was promulgated in Sopore town as a precautionary measure," Deputy Commissioner of Baramulla Baseer Ahmad Khan said.

The move came after thousands of people took to the streets at Bomie-Sopore and staged a massive demonstration this morning demanding punishment for security personnel, who allegedly fired at the youths on Saturday evening in which Mohammad Amin Tantray and Javid Ahmad died and Firdous Ahmad was injured.

The protesters carrying the body of one of the deceased also demanded withdrawal of troops from the area.

Meanwhile, a FIR under section 302 was lodged against the army at the Sopore police station, police sources said.

The army has also ordered an inquiry into the incident, a spokesman said. Police said the situation in the town was "tense" but under control.

Chief minister Omar Abdullah has ordered a magisterial inquiry into the incident and sought for a report within 15 days.

While locals allege army personnel moving in a bullet-proof vehicle resorted to firing at a place near a local bus stand without any provocation, the army said militants in combat dress opened fire to escape from security forces.

The incident sparked off massive protests in the town on Saturday evening following which paramilitary forces opened fire at the agitators, injuring five people, official sources said.

Meanwhile, acting chairman of Tehreek-e-Hurriyat Mohammad Ashraf Sahrai was placed under house arrest to stop him from visiting Sopore to lead the funeral of one of the two youths.

A police posse arrived at the residence of Sahrai in uptown Srinagar and asked him not to venture out of his house as he has been placed under house arrest, official sources said.

Chairman of moderate faction of Hurriyat Conference Mirwaiz Umer Farooq strongly condemned the killing of the youths and said "the incident at Sopore exposed the zero tolerance claim of the government".
