Srinagar has seen unrest for the past two months
At least 30 people have been injured in a grenade attack in Srinagar, the summer capital of Indian-administered Kashmir, police say.
The attack took place near a bunker of the security forces in the busy Budshah Chowk area of the city.
It is still not clear who was behind the attack.
Two months of demonstrations in the mainly Muslim Kashmir valley have left at least 40 people dead. This followed a period of relative quiet in the area.
Protests were initially triggered in June by a state government decision - later revoked - to transfer land in the valley to a trust which administers an important Hindu shrine.
They eventually developed into large-scale anti-India demonstrations.
The decision to drop the land transfer led to counter protests in the Hindu-majority Jammu area of Indian-administered Kashmir.
On 31 August the state authorities changed their minds again, saying 100 acres of land would be set aside for use by the Hindu trust - but only for the duration of the annual pilgrimage to the Amarnath shrine.
