Western intelligence agencies have accessed the computer and email account of Lashkar's communications chief, Zarar Shah, and found a list of possible targets, only 20 of which were in India.
According to a report in the Guardian, the LeT wanted to carry out such strikes beyond India to create terror. Shah and Lashkar operations chief Zaki-ur-Rehman Lakhvi, two of the main plotters of the Mumbai carnage, are now in Pakistan Police custody.
Pakistan's decision to bring criminal charges against nine men accused of involvement in the Mumbai attack has partly placated Indian officials.
The US has been trying behind the scenes to co-ordinate intelligence exchanges between India and Pakistan.
Intelligence agencies have warned that Mumbai raises the spectre of a new style of terrorist assault when 10 heavily armed gunmen created mayhem for three days and brought the city of 19 million people to a halt.
Nine of the gunmen were killed, but the lone survivor has given Indian investigators a full confession that the assault was planned in Pakistan by LeT.
There has been some speculation that raids in Spain in which netted 12 men including an Indian and 11 Pakistanis arrested were a result of the investigations into Lashkar's role in the Mumbai attacks.
