The police commissioner of Pune City in India has confirmed the use of a powerful explosive called RDX in the blast at a popular German bakery that occurred on Saturday.

The bomb killed at least nine people in the country's first big attack since the 2008 Mumbai massacre.

One more person, who was a college student, succumbed to his injuries, increasing the death toll to ten.

The bomb was reportedly hidden in a bag left behind at the bakery.

The Pune blast appears similar to a wave of bombs that hit Indian cities in the year before the Mumbai attacks that claimed the lives of more than 100 people.
