NEW DELHI — A Pakistani militant group apparently used an Indian operative as far back as 2007 to scout targets for the elaborate plot against India's financial capital, authorities said Thursday, a blow to Indian officials who have blamed the deadly attacks entirely on Pakistani extremists.
As investigators sought to unravel the attack on Mumbai, stepping up questioning of the lone captured gunman, airports across India were put on high alert amid fresh warnings that terrorists planned to hijack an aircraft.
Also Thursday, police said there were signs that some of the six victims of the attack on a Jewish center may have been tortured. "The victims were strangled," said Rakesh Maria, a senior Mumbai police official. "There were injuries noticed on the bodies that were not from firing."
Members of an Israeli rescue group that had a team in Mumbai said it was impossible to tell if the bodies had been abused, however, because no autopsies were conducted in accordance with Jewish tradition.
The surviving gunman, Ajmal Amir Kasab, 21, told interrogators he had been sent by the banned Pakistani militant group Lashkar-e-Taiba and identified two of the plot's masterminds, according to two Indian government officials familiar with the inquiry.
Kasab told police that one of them, Zaki-ur-Rehman Lakhvi, Lashkar's operations chief, recruited him for the attack, and the assailants called another senior leader, Yusuf Muzammil, on a satellite phone after hijacking an Indian vessel en route to Mumbai.
The information sent investigators back to another reputed Lashkar operative, Faheem Ansari, who they hope could be key in pulling together different strands of the investigation.
Ansari, an Indian national, was arrested in February in north India carrying hand-drawn sketches of hotels, the train terminal and other sites that were later attacked in Mumbai, said Amitabh Yash, director of the Special Task Force of the Uttar Pradesh police.
During his interrogation, Ansari also named Muzammil as his handler in Pakistan, adding that he trained in a Lashkar camp in Muzaffarabad — the same area where Kasab said he was trained, a senior police officer involved in the investigation said.
Secretary of State Condoleezza Rice met in Islamabad Thursday with Pakistani leaders, a day after meeting with Indian leaders, to urge that the two countries work together to find the attackers and bring them to justice.
