NEW DELHI: Nearly 45 people, including five women and seven students, were killed and another 50 injured in two explosions at a crowded park and a popular eatery in Hyderabad, three months after the Mecca Masjid blasts, police said.

The week-end outing at the popular Gokul Chat shop at Kothi locality turned into a tragedy when a deafening explosion ripped through it killing 32 people and wounding 21, they said. Five minutes earlier, 12 people, most of them from outside the state, were killed and 29 injured in another blast in an open air auditorium in Lumbini Park near the state secretariat in the heart of the city when a laser show was underway, they said.

The blast at the auditorium, where 500 people were present, was so powerful that some bodies were flung in the air. Among the dead at the Lumbini Park were two students from Ahmedabad. Security agencies are suspecting that Pakistan-based terror outfits like Laskhar-e-Taiba or Jaish-e-Mohammad may be behind the deadly Hyderabad blasts, the government said on Monday.

 "Investigations into this incident are in a very, very preliminary stage and based on some information so far some possibilities have been identified and expressed," Union Home Secretary Madhukar Gupta said here.

"These elements or organizations are clearly outside the country and they resort to fuelling such kinds of activities." he told reporters here after flagging off a BSF mountaineering expedition. Asked if any group has been identified, he said while the probe was in its initial stages, security agencies and state police were suspecting the role of Laskhar-e-Taiba or Jaish-e-Mohammad.

"But what is more important is to nab those who planned it and those who executed it," he said. His comments came a day after Home Minister Shivraj Patil refused to specify whether terror groups based in Pakistan and Bangladesh were behind on the Saturday night attacks. The Hyderabad Police say the explosives used in the blasts were manufactured at the Amin Explosives factory in Nagpur.

 They say they have definite clues that Neogel 90 — an ammonium nitrate based explosive used in the Hyderabad blasts — was manufactured at the factory. The guards at the gates even seemed hesitant to admit that it was an explosives factory. "There’s no farmhouse here. There’s a godown. I don’t know what’s made here," says an employee at the factory.

Nagpur is a hub of explosives manufacturers, but of late, the explosives produced here have been finding their way into the wrong hands. Just two months ago, the Nagpur rural police arrested five people and recovered a large amount of ammonium-nitrate based explosives. The Nagpur Police even admits that a big consignment of ammonium nitrate was sent to Hyderabad twice recently.

Says Nagpur Police Commissioner, Satyapal Singh, "Two consignments were sent to Hyderabad’s Rajshree Chemicals twice." It’s not just this link which is giving sleepless nights to the local police. A Nagpur link has come to light in several other cases, like the Malegaon blasts.
