India's prime minister, Manmohan Singh, says his government will do everything it can to find out who planted the three bombs that struck Mumbai on Wednesday.

The explosion left 18 people dead and more than a 100 injured. Initial investigations suggest the bombs were made of ammonium nitrate and triggered by mobile phone alarms.

India's financial capital has been attacked eight times but past investigations have led to minimal convictions.

Al Jazeera's Prerna Suri went to meet one family affected by the latest blasts.
