India may snap business links with Pak: Chidambaram

India may break off business, transport and tourist links with Pakistan if it fails to help to investigate the Mumbai attacks, Home Minister P Chidambaram has warned, pressing Islamabad to "cooperate soon."

"There are many, many links between India and Pakistan, and if Pakistan does not cooperate and does not help to bring the perpetrators to heel, those ties will become weaker and weaker and one day snap," Chidambaram told The Times daily.

"Why would we entertain Pakistani business people? Why would we entertain tourists in India? Why would we send tourists there?"

Chidambaram refused to discuss when such measures might be introduced, but said: "We need cooperation soon."

Accusing Islamabad of doing nothing to bring to justice the perpetrators of the Mumbai attacks blamed on the Pakistan-based Lashkar-e-Toiba, Chidamabaram said Islamabad has provided "nothing" so far after New Delhi handed over a dossier of evidence linking elements within that country to the Mumbai terror attacks of November 26.

Asked what Pakistan was doing to help with the investigation, Chidambaram said: "Zero. What have they provided? Nothing."
