Attribution of the 2008 Mumbai attacks was made by the Indian authorities who said that the Mumbai attacks were directed by Lashkar-e-Taiba militants inside Pakistan. American intelligence agencies also agree with this attribution.Pakistan initially contested this attribution, but agreed this was the case on 7 January 2009.To back up its accusations, the Indian government supplied a dossier to Pakistan's high commission in Delhi. The Pakistan government dismissed the dossier as "not evidence," but also announced that it had detained over a hundred members of Jamaat-ud-Dawa, a charity linked with Lashkar-e-Taiba. In February 2009, Pakistan's Interior Minister Rehman Malik agreed that "some part of the conspiracy" did take place in Pakistan.
Moreover, Indian government officials have said that the attacks were so sophisticated that they must have had official backing from Pakistani "agencies", an accusation denied by Pakistan.
The Mumbai attacks were directed by militants inside Pakistan, and carried out by ten well-trained Pakistani attackers who traveled to Mumbai by sea from Karachi via a hijacked trawler.Nine of the attackers were killed and one, Ajmal Amir, was captured alive.
Moreover, Indian intelligence sources increasingly accuse Lashkar-e-Taiba, a Pakistan-based terrorist group, which is the organization that the Mumbai Police assert planned and executed the attacks. They also say that former officers from the Pakistan Army and Pakistan's powerful ans secretive Inter-Services Intelligence (ISI) intelligence agency helped train the Mumbai attackers.Police are also looking into possible Indian collaborators, also trained in Pakistan Four former ISI officers have been requested by the U.S. to be placed on the UN Consolidated List of terrorists, which will permit sanctions on their bank accounts,as well as the Interpol wanted list.Police are also looking into possible Indian collaborators, also trained in Pakistan.
The names and photographs of the ten attackers and their hometowns in Pakistan were released by Mumbai police on 9 December.All were from Punjab except Ismail Khan, who was from Dera Ismail Khan in the North-West Frontier Province.Their names were difficult to establish because the alleged trainers of the attackers maintained "a system of changing the names of the members every few months, so that everyone had layers of names that were discarded over time."Some of the terrorists booked a room in the Taj hotel posed as students using forged Mauritian identity documents and credit cards, but there is no evidence any of them were actually from Mauritius, which is an Indian Ocean island nation.
