Washington: The US is trying to identify terrorist threats or plans hidden in the huge cache of material recovered from the hideout of slain al-Qaeda chief Osama bin Laden, an official has said.

"The top priority is to identify any threat information and to broadcast it widely within the US government and with our foreign partners. Of course, other top priority is to exploit the information to attract leads to other members of al-Qaeda," the intelligence official said on condition of anonymity.

The CIA, which has set up a task force, to go through every piece of material obtained during the raid, said that the US is still cataloging them.

The official however did not give the quantity of material obtained during the raid, except for saying that most of the information would however remain classified for long.

In one of the audio-less video which was released by the US on Saturday, Laden was very critical of the US and denigrating capitalism, according to the official.

This week, the US Department of Homeland Security issued a general alert about security of railway and mass transit systems in large cities, which was based on the information obtained from these materials.

Because of the sensitivity of the information, US officials are very selective on sharing the information obtained from these materials, including the cell phone and numbers obtained.

From these materials, he said the US is looking at close links between al-Qaeda and other terrorist outfits like Lashkar-e-Taiba and Jaish-e-Mohammed.

"I am not in a position to say at this time. We have shared information with foreign countries, but I am not going to say which ones," the official said.

Noting that al-Qaeda financing is an important factor, he said the US is looking into any insight that these materials could provide about the terrorist outfit's funds.
