NEW DELHI: A senior Indian official says investigators have found two unexploded bombs in the same area where a series of small blasts went off in the western city of Pune.   

Four small explosions struck the city Wednesday night.

One person suffered minor injuries.

Home Secretary RK Singh told reporters in New Delhi on Thursday that investigators have found two unexploded devices near where the blasts took place.

He said the fact that all of the blasts went off within 500 meters and within 45 minutes of each other showed there was planning behind them.

A cafe popular with foreigners in Pune was the site of a 2010 bombing that killed 17 people.
