Three rebels, a counterinsurgency police officer and an army soldier were killed during a gunbattle in Kashmir, officials said.
It occurred as shops and businesses shut down to protest against a sweeping and ongoing crackdown against activists seeking the end of Indian rule in the disputed region.
The fighting triggered large anti-India protests and clashes as hundreds of residents thronged the village of Turigam in the southern Kulgam area while barraging troops with stones.
An army officer and two other soldiers were injured in the fighting, which was still raging.
Government forces opened fire with shotguns and tear gas to quell the protesters, injuring at least half a dozen civilians, residents and emergency workers said.
Police and paramilitary soldiers also patrolled streets in Srinagar, the region's main city, and enforced a security lockdown in its downtown area in anticipation of protests and clashes.
Carrying automatic rifles and wearing riot gear, soldiers and police erected iron barricades and laid razor wire on roads and intersections to cut off neighbourhoods.
Police are mainly targeting Kashmir's largest political-religious group, Jama'at-e-Islami. The group is dedicated to the right to self-determination for the Himalayan region, which is divided between India and Pakistan but claimed by both in its entirety.
Indian authorities have so far arrested at least 400 Kashmiri leaders and activists, escalating fears among already wary residents that a sweeping crackdown could touch off renewed anti-India protests and clashes. They are detained in police stations and jails across Kashmir.
Among those arrested were Jama'at-e-Islami head Abdul Hamid Fayaz and Mohammed Yasin Malik, an influential pro-independence leader who heads the Jammu-Kashmir Liberation Front.
The strike was called by the Joint Resistance Leadership, or JRL, which comprises three top Kashmiri leaders, including Malik.
Mirwaiz Umar Farooq, another JRL member, denounced the arrests and said India's latest crackdown would fail as "people won't give up their struggle for freedom."
"India is already at war with Kashmiris. Now they're warmongering with Pakistan. We again warn (Indian authorities) to de-escalate and talk as no force can push us into submission," Farooq said.
"There's a going to be serious ramification, a reaction to this (crackdown). It'll force more youngsters to armed militancy."
Tensions are high between India and Pakistan following the February 14 suicide car bombing of a paramilitary convoy by a local Kashmiri militant. Forty Indian soldiers died in the attack.
India quickly blamed the attack on Pakistan and promised a "jaw-breaking response."
Pakistan warned India against linking it to the attack without an investigation, and offered dialogue to resolve all issues, including Kashmir.
Residents fear the crackdown could be a prelude to a military strike by India against Pakistan or tinkering with Kashmir's special status in India's constitution. India's Supreme Court has yet to give its verdict on a petition against the special provision that it has been hearing for more than a year.
Indian authorities rushed about 10,000 additional paramilitary soldiers to the already highly militarised Kashmir Valley.
