Sources in the police told CNN-IBN RDX was packed on bicycles that were used as carriers to trigger off the blasts.
So a common military explosive then and not something mixed in the kitchen and bathroom from a recipe off the internet. RDX has been used by the group Lashkar-e-Toiba in the Mumbai train bombings of 2006 and is believed to have also been used in the 1993 bombs in Mumbai. These bombs seem to have been working from timers or remote control not suicide operatives.
All the blasts that took place in Jaipur on Tuesday were in affluent and predominantly Hindu localities.
This tallies with the pattern of community targeting that, beginning with the 1993 Mumbai serial blasts, was evident in 2006 when terrorists attacked first-class train compartments preferred by rich Gujarati businessmen in Mumbai and crowds that had gathered in front of Varanasi's Sankatmochan temple. Those who struck in Jaipur not just chose Tuesday but also a Hanuman temple while selecting the sites to plant explosives, timing the blasts to coincide with aarti.
Recognizing this, the Centre lost no time in asking all states to step up vigil in areas with a history of communal tension, and, fearing that terrorists might take advantage of a distracted security establishment, at vital installations.
The attackers were not looking just for a higher death toll, but also wanted to advertise their religious identity as part of their diabolic plot to pit communities against each other.
The Telegraph reports that Four people have been questioned by police in connection with seven bomb blasts that killed 80 people and injured 200 in the crowded markets of Jaipur in India.
The suspects were detained as police sifted through mutilated bodies and the remains of buildings following a series of bombs, which are thought to have been planted in rickshaws, bicycles and cars by Pakistani or Bangladeshi Islamist militants.
“We have picked them up for questioning in regards to the attacks last night, but we have not booked them on any charge,” a police spokesman said.
Authorities today announced a nationwide security alert and a day of mourning across the western desert state of Rajasthan as the full extent of the carnage emerged.
Shopping bags, bloodied sandals and shoes were strewn across the popular Johri bazaar where one of the bombs exploded.
Pools of blood stained the street outside Hanuman temple, dedicated to the Hindu monkey god. A bride in a red saree still wearing marriage bangles was among the dead. As was a 10-year-old boy.
The first explosion happened in a popular vegetarian restaurant in a crowded bazaar shortly after 7.30pm.
One suspect was detained and was being questioned, police said, adding that an eighth bomb that did not explode was found attached to a bicycle and defused.
While Indian officials did not immediately openly blame Pakistan-based militants for the attack, Sriprakash Jaiswal, the junior home minister, suggested the bombings were connected to previous explosions.
"The blasts are part of a big conspiracy," he said. "Obviously, it’s a terrorist plot," said A.S Gill, the local police chief. "The way it has been done, the attempt was to cause the maximum damage to human life."
The nearly simultaneous blasts bore the hallmarks of an attack by terrorists based in neighbouring Pakistan.
Indian intelligence sources said the bombs could have been the work of Islamist radicals who have been trying to infiltrate the disputed state of Jammu and Kashmir from Pakistani territory in the last two days.
