On 13 July 2011 between 18:54 and 19:06 as per IST blasts occurred at the Opera House, at Zaveri Bazaar and at Dadar West localities, leaving 26 killed and 130 injured.
The first device was planted on a motorcycle at Khau Galli in south Mumbai's Zaveri Bazaar and exploded at 18:54 local time. The second device, planted in a tiffin box outside Prasad Chambers and Panchratna Building, in the Opera House area on Charni Road, exploded at 18:55, the area of workplaces of 5,000–6,000 people connected with the diamond-trade industry.
A third device was placed on an electric pole at Dr Antonio Da Silva High School BEST bus stand near Kabutar Khana in the Dadar area and exploded at 19:06 pm
Following the blasts, phone lines jammed and communications ceased or were available intermittently for at least a few hours. Other metropolitan cities, including Delhi, Chennai, Hyderabad and Bangalore, were also put on high alert.
Most of the injured were rushed to various hospitals in Mumbai, including J.J. Hospital, St. George Hospital, Hurkisondas Hospital and G.T. Hospital.
Mumbai has been hit by terrorist incidents at least half a dozen times since the early 1990s, with over 600 people dying in these attacks. A loss of Rs. 3 billion per day was reported at the closure of the Panchratna Building, after the blasts, where the people who lost their lives were mainly from the diamond industry, and at Zaveri Bazaar, were mostly goldsmiths.
Speculation has focused on the Indian Mujahideen.
Lashkar-e-Taiba has also been mentioned as another possibility by Indian press reports. The Indian Mujahedeen (IM) is closely affiliated with the Student Islamic Movement of India (SIMI), which emerged in the late 1970s.
The Indian Mujahedeen is opposed to Hindu nationalism, has endorsed al Qaeda's goals and agenda, and seeks to avenge violence against Muslims in India, as well as protest the lack of socioeconomic opportunities for Muslims within Indian society.
