NEW DELHI, India -- As the death toll climbed to 59, investigators combed through piles of rubble yesterday for clues to the identities and methods of those responsible for bombings that rocked the Indian capital during preparations for a major Hindu holiday.
Jittery customers trickled back to busy shopping districts hit by the blasts. Police heightened security throughout the city and scurried to respond to several reports of suspicious packages, including one at a school for the blind. None turned out to be a threat.
Home Secretary Shivraj Patil said that investigators had gathered "lots of information" about Saturday's three bombings, which struck two crowded markets and a public bus within half an hour. In addition to the 59 killed, 210 people were injured.
Patil declined to describe the nature of the leads or to name possible suspects, but attention increasingly focused on the Islamic militant group Lashkar-e-Tayyaba, based in the contested region of Kashmir. A small, lesser-known separatist group called Islamic Inquilab Mahaz telephoned a Kashmiri news service to claim responsibility for the explosions.
Police characterized the group as a small outfit in existence since 1996 but not very active of late. There was immediate speculation that the group was linked to or a front for Lashkar-e-Tayyaba.
Analysts say that Lashkar-e-Tayyaba, or Army of the Pure, is one of the few militant groups operating in India that would have been capable of organizing a precisely timed, large-scale attack. The group was implicated in the last major strike on New Delhi, an assault on Parliament in 2001 that nearly sparked a fourth war between India and its longtime rival and fellow nuclear power Pakistan.
The two nations have since engaged in a slow-moving peace process. The most recent sign of progress was yesterday's announcement of an agreement to open several crossing points in Kashmir for families and relief groups struggling to deal with the aftermath of the Himalayan region's devastating Oct. 8 earthquake.
Analysts said the bombers might have been aiming to disrupt the peace process. Kashmiri armed groups might also have wanted to dispel widespread reports that their membership and operations had been crippled by the quake.
"It becomes incumbent upon them to prove their capabilities," said Ajai Sahni, executive director of the Institute for Conflict Management in New Delhi. "It's part of the effort to keep Kashmir up in the headlines and to keep applying pressure on India wherever possible."
The attack came during one of the busiest shopping periods of the year, just before Diwali, the Hindu festival of lights. Shoppers are out buying dried fruit, jewelry and other gifts to mark the holiday. This week, Muslims will celebrate Eid al-Fitr, the end of Ramadan.
Most merchants in Paharganj and Sarojini Nagar, the two market areas targeted in the bombings, opened for business as usual yesterday.
In Paharganj, in the heart of the city, fewer shoppers than expected at this time of year strolled the street -- almost equaled in number, it seemed, by those who came to view the cleanup operations at the bomb sites. A few cows wandered up and down the lane.
Police officers wielding stout bamboo poles were thick on the ground, stopping to question taxi drivers or anyone else who appeared to be lingering.
"It is very risky to open, but ... it is festival time. We have to open the shop. It is a must," said Mukesh Kumar, 50, whose family has sold gold and silver trinkets in the market for half a century.
The windows of his store, which look out on the spot where the first of the three bombs went off early Saturday evening, were blown out. His brother and sister-in-law, who were minding the shop at the time, escaped injury.
Next door, R.K. Chawla, 40, proprietor of the Jack & Jill Overseas crafts shop, vowed to stay on in Paharganj, out of defiance and resignation to the uncertainties of life.
