Surat, July 29: Surat Police today recovered two more live bombs, two days after serial bomb blasts killed over 40 people in Ahmedabad.

According to police officials, one bomb was found near the Labheshwar Police Chowki in the city''s Varachha area, while the second bomb was found in Santoshi Nagar.

The bomb disposal squad are at the site looking for further clues.

On Monday, three live bombs were defused in Surat.

Meanwhile, Ahmedabad Police and officials of other investigative agencies are coming around to the view that the banned Student Islamic Movement of India (SIMI) could be behind this latest attack

Police have said that they are interrogating several people in connection with the Ahmedabad attacks, but added that only one person has been taken into their custody so far.

As with previous serial blasts, whether in Jaipur or Varanasi, investigators are yet to make tangible headway, despite recovering two cars packed with explosive material in Surat.

Parallels are being drawn with the May 13 Jaipur blasts in which the vehicles of death were the ubiquitous "aam admi" mode of transport - bicycles and table clocks with timers.

Intelligence experts also believe that there is a link with the Bangladesh-based Harkat-ul-Jihad al-Islami and Al-Qaida-linked Lashkar-e-Toiba.

Police say the scale of Saturday''''s attacks would have needed a network of more than 50 terrorists; something only a SIMI-HuJI combine could deliver.

Police also suspect ammonium nitrate and LPG bottles were used for maximum impact in the two bombs that went off at LG Hospital and Civil Hospital.

Police say 5kg LPG cylinders were strapped along with the ammonium nitrate mix to create greater heat and power.

On Monday, relatives mourned the loss of their loved ones while struggling to cope with the tragedy. (ANI)
