At least eight people have been killed and 30 wounded in a series of grenade attacks in Indian-administered Kashmir's summer capital, police say.
Tourists are being increasingly targeted
Seven of those killed in the five blasts in Srinagar were tourists.
In one incident, suspected militants threw a grenade inside a tourist bus, police chief SM Sahay told the BBC.
No group has said it carried out the attacks. Tourists, returning to the state after years of violence, have now been targeted four times this year.
Correspondents say cheap flights have helped draw tourists back to Kashmir, where houseboats and hotels are booked to capacity for the first time in years.
But with tourism booming, the visitors have become an easy target for militants opposed to Indian rule.
Series of blasts
Mr Sahay said one man, suspected of involvement in the attacks, had been arrested and was being questioned.
Security has been tightened across Indian-administered Kashmir and police are searching vehicles.
The biggest of the day's attack took place by Dal Lake in the heart of Srinagar when a vehicle carrying tourists from the Indian state of West Bengal was attacked.
"As we were passing Dal Lake, a round object was thrown in from the window," one of the victims, Shambhu Dutta, told the BBC.
"There was a huge explosion," Mr Dutta, whose wife Purnima was also injured, said.
Three of those killed were women. Twelve people were injured.
The second attack took place in the city's Regal Square - a busy market area in the heart of Srinagar - which left four people injured.
One person was killed and 11 people, including two children, were wounded in two other attacks which followed soon after in the busy Lal Chowk area.
In May, more than 30 Indian tourists were injured in a grenade attack on a passenger bus travelling from Srinagar to the resort town of Gulmarg.
Four tourists, including a woman and a child, were killed in a similar attack just days earlier.
