The 2011 Mumbai bombings (often referred to as 13 July or 13/7) were a series of three coordinated bomb explosions at different locations in Mumbai, India, on 13 July 2011 between 18:54 and 19:06 IST. The blasts occurred at the Opera House, Zaveri Bazaar, and Dadar West localities, leaving 26 killed, and 130 injured.

The first device was planted on a motorcycle at Khau Gali in south Mumbai's Zaveri Bazaar and exploded at 18:54 local time. The second device, planted in a tiffin box at the Opera House near Charni Road, exploded at 18:55. The third device was placed on an electric pole at a Kabutar Khana bus stand in Dadar area and exploded at 19:06.

Following the blasts, phone lines were jammed and communications ceased or were available intermittently for at least a few hours. Other metropolitan cities like Delhi, Chennai, Hyderabad and Bangalore were also put on high alert. Immediately after the blasts, the Mumbai Police sent an SMS to a few mobile phone users in Mumbai reading "Bomb blasts reported at Zaveri Bazaar, Dadar. Please be careful. Stay indoors. Watch news channels". Most of the injured were rushed to various hospitals in Mumbai, such as J.J. Hospital, St. George's Hospital, Harikishandas Hospital and G.T. Hospital.

Terrorism in India is primarily attributable to religious communities and Naxalite radical movements.^{[citation needed]}

The regions with long term terrorist activities today are Jammu and Kashmir, Mumbai, Central India (Naxalism) and the Seven Sister States (independence and autonomy movements). As of 2006, at least 232 of the country’s 608 districts were afflicted, at differing intensities, by various insurgent and terrorist movements. In August 2008, National Security Advisor M K Narayanan has said that there are as many as 800 terrorist cells operating in the country.

Mumbai has been the most preferred target for most terrorist organizations, primarily the separatist forces from Pakistan.^{[citation needed]} Over the past few years there have been a series of attacks, including explosions in local trains in July 2006, and the most recent and unprecedented attacks of 26 November 2008, when two of the prime hotels, a landmark train station, and a Jewish Chabad house, in South Mumbai, were attacked and sieged.^{[citation needed]}

Mumbai /mʊmˈbaɪ/, also known as Bombay /bɒmˈbeɪ/, is the capital of the Indian state of Maharashtra. It is the most populous city in India, and the fourth most populous city in the world, with a total metropolitan area population of approximately 20.5 million. Along with the neighbouring urban areas, including the cities of Navi Mumbai and Thane, it is one of the most populous urban regions in the world. Mumbai lies on the west coast of India and has a deep natural harbour. In 2009, Mumbai was named an Alpha world city. Mumbai is also the richest city in India, and has the highest GDP of any city in South, West or Central Asia.

The seven islands that came to constitute Mumbai were home to communities of fishing colonies. For centuries, the islands were under the control of successive indigenous empires before being ceded to the Portuguese and subsequently to the British East India Company. During the mid-18th century, Mumbai was reshaped by the Hornby Vellard project, which undertook the reclamation of the area between the seven constituent islands from the sea. Completed by 1845, the project along with construction of major roads and railways transformed Bombay into a major seaport on the Arabian Sea. Economic and educational development characterised the city during the 19th century. It became a strong base for the Indian independence movement during the early 20th century. When India became independent in 1947, the city was incorporated into Bombay State. In 1960, following the Samyukta Maharashtra movement, a new state of Maharashtra was created with Bombay as capital. The city was renamed Mumbai in 1996.

Aishwarya Rai, known also as Aishwarya Rai Bachchan after her marriage (Tulu pronunciation [əjɕʋərjaː rəj]; born 1 November 1973) is an Indian film actress. She worked as a model before starting her acting career, and ultimately won the Miss World pageant in 1994. Rai has featured in films in various languages including Hindi, English, Tamil, Telugu, and Bengali.

Often cited by the media as the "most beautiful woman in the world", Rai made her acting debut with Mani Ratnam's Tamil film Iruvar (1997), and had her first commercial success in Jeans (1998). She found success in Bollywood with Sanjay Leela Bhansali's Hum Dil De Chuke Sanam (1999) and Devdas (2002) and eventually won two Filmfare Awards in the Best Actress category.

After a series of unsuccessful films during 2003–2005, she appeared in the blockbuster action thriller Dhoom 2 (2006) and subsequently featured in such films as Guru (2007), Jodhaa Akbar (2008), and Enthiran (2010). She gained critical acclaim for her performances in offbeat, independent films such as Chokher Bali (2003), Raincoat (2004), and Provoked (2007). Rai has thus established herself as one of the leading contemporary actresses of Indian cinema.
