Washington, Jan 12 (AP) The FBI had warned that extremists were preparing to come to Washington, attack Congress and engage in "war", according to a report in The Washington Post.

The report says the warning was issued internally by the FBI's field office in Norfolk, Virginia, a day before the violent riot at the US Capitol.

The warning directly contradicts statements from the Justice Department and FBI officials that they had no intelligence to suggest a storming of the Capitol.

The Post says the memo described how people had been sharing maps of the Capitol's tunnels and discussing rallying points to meet up to travel to Washington.

The newspaper reported that the document detailed posts calling for violence, including that "Congress needs to hear glass breaking, doors being kicked in, and blood from their BLM and Antifa slave soldiers being spilled."

It also said to "go there ready for war."

The Associated Press has not obtained the document.

The FBI did not immediately respond to a request for comment.(AP)
