The server from which an e-mail was sent a few hours after Sunday's Jama Masjid firing incident has been traced to Norway, Home Minister P Chidambaram today said.

"The e-mail that came a few hours after the firing has been traced to a server in a foreign country -- Norway," Chidambaram said.

In an interview to CNN, the Home Minister said the investigators have found that it was a SIM card purchased and put in a GPS activated mobile phone from which the e-mail, owing affiliation to terror group Indian Mujahideen, was sent.

"So we have leads but we have to zero on the particular person who sent it. (There is) nothing in the email itself which directly links it to the shooting (near Jama Masjid)," he said.

Ruling out a terror link in the incident in which two Taiwanese nationals were injured, Chidambaram said the e-mail seems to have been prepared many days in advance and it makes no direct mention of the shooting.

"We are not certain that the persons involved in the shooting are directly connected with the e-mail," he said.

Two motorcycle-borne unidentified people fired upon a group of foreign tourists in front of the Mughal era Jama Masjid.

A "crudely-circuited" pressure cooker bomb exploded some time after the firing, leading to panic in the area.

A few hours later, banned terror outfit Indian Mujahideen sent an e-mail to news organisations claiming responsibility for the incident and threatened terror strikes during the forthcoming Commonwealth Games.
