Two of 20 worshippers injured on Friday in a grenade attack outside a mosque in occupied Kashmir died in hospital on Saturday, while six more people were killed in separate violence, police said.
Twenty people were wounded on Friday when suspected freedom fighters hurled a grenade at the mosque in a congested area of occupied Jammu, occupation police said.
Several pro-India politicians were among the 200 worshippers in the mosque but they escaped unhurt. No group claimed responsibility for the attack.
Police said they stepped up security for top ministers and civil servants after the incident. Occupied Jammu functions as the state capital from November until April.
Police said suspected freedom fighters shot dead two of their colleagues in an "intergroup clash" in the southern Doda district late Friday. The motives behind the killings were not immediately known.
