Azam Amir Kasav, the lone surviving gunman told interrogators, he and the other nine attackers were in contact with Zaki-ur-Rehman Lakhvi, whom the United States says is the operations chief of the Pakistan-based Lashkar-e-Taiba (LeT) militant group. LeT is on US, UN and Indian terrorist lists. It has in the past had links with Pakistani intelligence. LeT terrorists are top suspects in the 2006 bombings on Mumbai trains, and a 2001 attack on Parliament.
Kasav told interrogators he and the other terrorists spoke to Lakhvi and other LeT leaders during their boat journey to Mumbai and also while they battled commandos inside two Mumbai hotels, where most of the 171 people who died in the attacks were killed.
According to two senior Mumbai police officials involved in the investigations, information on several calls made to Pakistan was contained on a satellite telephone found on a fishing boat hijacked and used by the gunmen on their journey to Mumbai.
"They were given directions like where to land the dinghy, where to keep the bombs," said a security official, referring to the small boat the attackers used to come ashore in Mumbai. They also found a GPS navigation device that had a route plotted back to Karachi, the officials said.
Kasav, who agreed to come to Mumbai on the promise of cash for his poor family, told officers that their handlers gave them "strategic advice" about the operation over the telephone and directed their movement, one of the officers told Reuters.
The 21-year-old militant, who said he was from Faridkot of Pakistan's Punjab province, also told investigators Lakhvi was among those who had briefed them about the targets in Mumbai.
Pakistani President Asif Ali Zardari has said he doubts Kasav is a Pakistani, and has said that anyone found complicit in the attacks will be tried in Pakistan.
