Two bomb blasts killed 40 people and injured over 80 on Saturday evening at the Lumbini amusement park and a food stall in the Kothi area in the South Indian city of Hyderabad, capital of the state of Andhra Pradesh.

The blasts are said to have occured around 7:40PM local time within minutes of each other.

The first blast hit an open-air auditorium in the Lumbini park during a laser show about the history of the city and the second occurred at a food stall called Gokul Chaat.

Police found 19 unexploded bombs in different areas of the city including the Venkatagiri Theater and Musarram Bagh.

The state government suspects the involvement of Islamic militants from neighbors Pakistan or Bangladesh in the blasts.

This is the second major blast in Hyderabad. On May 18, 2007, blasts hit the Mecca Masjid mosque in the city, killing 16 and injuring 56 people.

Hyderabad has been growing into a major center for leading information technology, pharmaceutical and biotech firms.

Microsoft, Dr.Reddy’s Labs and Bharat Biotech are some of the companies that have significant operations in this city of seven million.

Hyderabad has a long history of communal violence between the majority Hindus and minority Muslims.

Muslims account for about 30% of the city’s population.
