Seven bombs exploded in close succession in the western Indian city of Jaipur on Tuesday evening killing at least 45 people and injuring 100 other, local authorities said.

The bombs, which were detonated within a few minutes of each other, exploded in crowded areas of the Indian city. One of them exploded near a temple dedicated to the Hindu monkey god, Hanuman. The area is frequently visited by tourists as well as the other areas where bombs exploded: the popular 18th-century tourist site, Hawa Mahal, and the Johri Bazaar, lined with jewelers.

According to other estimations, the death toll of the incident was lower. NDTV news channel estimated that at least 35 people died in the series of blasts. 20 people were confirmed dead by the city police.

The country’s Junior Home Minister Shri Prakash Jaiswal addressed the nation through a local TV station and said the explosions were caused by bombs.

"I heard a deafening noise and I thought it was a (gas) cylinder blast," witness Hemanth Modi told the NDTV news channel. "There was smoke and I could not find my son. Then I found him."

Police said the bombs went off within a radius of 50 feet and they had been planted in the wheels of bicycles. The explosions caused panic in the narrow streets of the city.

The bomb attack wasn’t claimed yet.

Authorities issued high alerts in the Indian capital New Delhi and the country's financial capital Mumbai in anticipation of other possible bomb attacks.
