A minor explosion has rocked bustling commercial street Begum Bazar in Hyderabad on Monday. At least four persons were critically injured in the mishap. The injured persons were immediately rushed to a nearby hospital. Cops and dog squads have swiftly plunged into the action.  There has been no information so far as to what led to the explosion. The sources said police might ascertain the reasons for blasting in some time.

It has to be mentioned that Begum Bazaar lies in the heart of the city. It's one of the busiest commercial streets. Any untoward incident here can literally claim a large number of lives, said a social activist. This blast took place barely within a week of Pune blasts. The sources said the ministry of home affairs (MHA)  was looking into Pune explosions and in meantime another explosion took place in Hyderabad.
