India imposed a curfew in parts of Kashmir and deployed thousands of troops on Tuesday after soldiers killed two youths during protests.
Eight Kashmiri civilians have now been killed in incidents involving Indian security forces in less than three weeks, with each death sparking further protests.
Indian troops on Monday shot dead two Kashmiris during protests in the latest of a series of fatal attacks.
A 22-year-old Muslim man was killed and three others injured in the firing. Another, nine-year-old Tariq Ahmad was killed when security forces opened fire to disperse a demonstration.
Police and paramilitary soldiers in riot gear patrolled deserted streets in Srinagar, the capital of the mainly Muslim Kashmir, and warned residents to stay indoors, witnesses said.
At least 13 people were injured in fresh clashes between protesters and security forces across the valley, police said.
"The discontent and alienation is in its peak now in Kashmir, and I don't see the government making any serious efforts in addressing it," said Noor Ahmad Baba, dean of social sciences at Kashmir University.
More than a dozen groups have fought Indian forces since 1989, seeking independence for the Muslim-majority state or its merger with Pakistan.
In 1948, the United Nations adopted a resolution calling for a referendum for Kashmir to determine whether the Himalayan region should be part of India and Pakistan. Kashmiris say fight against India since it rejected to hold referendum in Kashmiri territory.
India already maintains a massive troop presence in Kashmir.
