NEW DELHI — In the days after the deadly Mumbai attacks, India demanded that Pakistan crack down on militants, shutter charities linked to extremists and jail suspected plotters.
With a flurry of raids, Pakistan took many of those steps last week. Now it's up to India to do what it likes least: share intelligence with its arch rival about what it knows and how it knows it.
Keeping the alleged plotters in jail will require unprecedented investigative cooperation across a border mined with distrust and suspicion, and the onus has shifted to India.
Pakistani authorities say they will prosecute in their own courts anyone linked to the three-day siege in Mumbai that left 164 dead — they just need the proof.
"Our own investigations cannot proceed beyond a certain point without provision of credible information and evidence," said Pakistan's foreign minister, Shah Mehmood Qureshi.
But Indian Foreign Minister Pranab Mukherjee said it was too early to share any of what investigators say is ironclad evidence tying the attacks to Pakistani soil. According to India, the 10 gunmen were from Pakistan, as were the handlers, masterminds, weapons, training camps and financing.
"Whatever evidence we have, we can make available," Mukherjee told Indian news channel CNN-IBN in an interview to be broadcast today. "We are also investigating. We have not come to any conclusion. Therefore, at this juncture, perhaps it would be premature to share the evidence."
It remains uncertain how much evidence, if any, India will actually provide.
India finds itself in the awkward position of having to investigate the terrorist attacks hand-in-hand with its longtime nemesis. The two countries have fought three wars against each other since independence. Despite a peace process that began in 2004, tensions remain high.
Much of India's information comes from Mohammed Ajmal Kasab, the lone captured gunman. Through repeated interrogations, he has said he was trained by Lashar-e-Taiba, a banned Pakistan-based militant group, and revealed key details such as names of fellow plotters and locations of camps.
Islamabad has refused to even acknowledge that Kasab is Pakistani, complaining it has had to rely on news reports for information.
A Pakistani newspaper, Dawn, tracked down Kasab's family in the village of Faridkot — his hometown according to Indian investigators — and said the suspect's father had identified his son from photographs of the gunmen.
Pakistan has taken action in recent days, closing 65 offices of a charity linked to militants, putting the charity's prominent founder under house arrest and arresting senior Lashkar leaders, including the attacks' suspected mastermind.
