At least seven people have been killed in two separate bomb explosions in Muslim-dominated neighbourhoods in western India, police say.
Five people died in a blast near a mosque in Malegaon, about 260km (160 miles) from Maharashtra's state capital, Mumbai.
Two others were killed in an explosion in the town of Modasa in the neighbouring state of Gujarat.
India has been hit by a number of explosions in recent weeks.
Nobody has claimed responsibility for the latest attacks which happened on Monday night.
In the Malegaon attack, more than 100 people, including policemen, were injured.
Two years ago, at least 37 people were killed and more than 125 others injured in bombings at a Muslim graveyard in the town.
In October 2001, violent protests against the US attacks on Afghanistan left a total of 12 people dead in Malegaon.
Security has been tightened in the area.
In the Gujarat attack, police said two men on a motorcycle dropped a bag containing a bomb in a crowded market.
The bomb went off when a local resident picked up the bag.
A similar incident happened over the weekend in Delhi when a bomb blast at a market killed one person and injured at least 15 others.
Cities across India have been on high alert after recent attacks.
The government says its main concern is to stop religious violence flaring up and has asked people to keep calm.
Two weeks ago, five bombs ripped through busy shopping areas in Delhi, killing at least 20 people. Nearly 50 were killed in Ahmedabad in July.
Some of the attacks have been claimed by a group calling itself the Indian Mujahideen. Police say they have arrested its leader, Mohammed Arif Sheikh.
In separate violence, one person was killed in rioting between Hindus and Muslims in the Mumbai suburb of Thane on Monday night. The death followed arguments over putting up a display for the Hindu festival of Navaratra.
