Al Qaida was considering targeting oil tankers in terror attacks to damage Western economies, US officials have said.
The terror group was looking at plots to hijack oil tankers in non-Muslim waters and blow them up, according to a leaked intelligence bulletin.
There is no intelligence pointing to a specific plot or threat.
It was not immediately clear whether the details about the plot were coming from Osama bin Laden's compound.
US intelligence officials are sifting through a treasure trove of information coming out of materials taken from the former terror leader's hideout in Pakistan earlier this month after he was shot and killed by Navy Seals.
