MUMBAI (AFP) - The attackers who herded together selected hotel guests during their attack on Mumbai never intended to keep any hostages alive, a top commando official said Sunday. "At no stage did we get any demand from the side of the terrorists," the head of the elite National Security Guard (NSG), JK Dutt, told reporters. All the "senseless killings" in the Taj and Oberoi/Trident hotels had been carried out before commando units stormed the buildings, he added. Dutt said the holdout gunmen appeared to have a comprehensive knowledge of the Taj's layout as they were able to move from one place to another "without a misstep." Whenever the special forces units launched an offensive, the gunmen would set fire to the curtains of a hotel room to create a diversion, before moving on to a new hiding place. Dutt said the assailants appeared to have been very well trained from the way they constantly moved around the hotel building, making it difficult to pin them down. Indian intelligence sources told AFP that eight of the attackers involved in the attack had arrived in Mumbai a month ago. They rented a house and conducted "extensive reconnaissance missions." Sources claimed there were also believed to be other infiltrators who stockpiled arms and ammunition, including in one of the two luxury hotels that were attacked. They were joined on Wednesday evening, when the assault began, by a second group who reached Mumbai from the sea, the sources said. Meanwhile, Ajmal Amir Kamal, the only gunman captured during the attacks on Mumbai, has given testimony of the operation's links to a Pakistan-based group, Indian Press reports claimed Sunday, quoting intelligence sources. Kamal is reportedly being interrogated in a safe-house in Mumbai. According to the sources quoted by several newspapers, Kamal, 21, has identified all the attackers as Pakistani citizens and acknowledged that they were trained by Lashkar-e-Taiba. He confirmed the attackers had come ashore at Mumbai in dinghies launched from a hijacked vessel whose crew had been killed, the sources claimed. US intelligence has also noted various indications of Lashkar involvement. "Some of the things that have been learnt thus far do point in the direction of a Kashmiri connection," a US counter-terrorism official told AFP. "At this point people are looking very hard at the Lashkar-e-Taiba," said the official, who declined to be identified. According to Zee News, in a startling revelation Kamal said that in all 15 gunmen had entered into Mumbai. While nine had been killed by the security forces, still five terrorists have been moving across the city. Kamal, who is still bed ridden with several bullet shots in his body, was sent to police custody till December 11 by a visiting judge. The channel claimed the satellite phone recovered from the abandoned trawler Kuber contains crucial terrorist information, and the calls traced from the satellite phone were made to LT chief Yahya and Zakirur Rehman. In addition, according to the report, satellite phones also contain the records of conversation made by Yahya in Bangladesh in addition to Jalalabad and Muzaffarabad. It is believed that it was Yahya who arranged fake IDs and SIM cards for Mumbai terror operation from Mauritius, US and UK, it said. He told Mumbai Police that the group that reportedly came out of Karachi via the sea route undertook their mission to avenge the death of Palestinians, and therefore, one of the main targets identified by them was Nariman House, which housed a Jewish synagogue visited by Israelis, reports claimed. The landmark Taj Mahal Palace Hotel was also targeted by the Faridkot resident and his fellow gunman with the objective of attracting the maximum global attention, as the venue had frequent foreign visitors and guests, reports said and added they also had plans to enter the Times of India building, but changed it after Qasab was fired upon by the police.
