Government says, it has promising but not conclusive leads in the Delhi High Court blast case. Home Minister P. Chidambaram told reporters in New Delhi on Friday that the leads are being pursued. He said, the person suspected to have sent an email claiming that the High Court blast was carried by HuJI has been traced and is being questioned. Indian Mujahideen, another terrorist outfit, has dismissed the HuJI claim that their terror outfit was responsible for the blast. The Home Minister said that it is difficult to say at this juncture if there is any involvement in the blast from across the border. But he said, India lives in a troubled neighbourhood as Afghanistan and Pakistan have become epicenters of terrorism. He said, the answer to such a challenge is to build capacity. Mr. Chidambaram said that home-grown terror modules are also active and it is a wake up call for the country. He said, an alert has been sounded across the country in view of the ensuing festival season. Reacting to the Opposition's criticism that Government agencies have failed to crack down the terrorist outfits, Mr. Chidambaram said he had expected opposition leaders to show greater bi-partisanship, maturity and statesmanship. Leader of the Opposition in the Rajya Sabha Arun Jaitley had earlier demanded stringent measures against terrorism. The Home Minister said that providing government jobs to the next of kin of those killed in the Delhi High Court blast is under active consideration of the Government. Meanwhile, security has been strengthened in Ahmedabad following the receipt of an email by Delhi Police which threatens of a blast in Ahmedabad. The e-mail purportedly sent by Indian Mujahideen, speaks about the next target in a coded language, interpreted to be Ahmedabad.
