According to the Pentagon, Military prosecutors have refiled terrorism and murder charges against the accused mastermind of the attacks on 9/11 along with four other men under a revamped trial process established at Guantanamo Bay, Cuba.

The charges against Khalid Sheikh Mohammed and the others allege that they were responsible for planning the attacks which included flying airliners into the World Trade Center buildings, the Pentagon, and a fourth plane that crashed in a Pennsylvania field.

Nearly 3,000 people were killed combined.

Prosecutors have recommended that the trial be a capital case, which could bring the death penalty.

The five men were charged previously in connection with the attacks, but those charges were dropped in 2009 when the Obama administration hoped to close the U.S. detention facility at Guantanamo and do away with Bush-era military commissions for trying terror suspects.

The men have been held at Guantanamo since their capture.
