A car bomb killed at least 10 people in the eastern Indian state of Punjab on Wednesday.
Police said the car was loaded with explosives and that a second vehicle was waiting nearby.
The blasts were reported around noon local time (0500 GMT) in the capital, New Delhi, according to the Indian Express.
Punjab is one of India’s most volatile states.
Authorities said they were searching for the two vehicles and the driver.
In February, two bombs exploded near a crowded market in the northern state of Rajasthan killing 14 people.
The latest attack comes amid rising tensions between India and Pakistan over the disputed territory of Kashmir.
