Defense Secretary Lloyd Austin revoked the plea agreements for the 9/11 terrorist attack mastermind Khalid Sheikh Mohammed and two others and relieved the official in charge of military courts in Guantanamo Bay.

The move puts the possibility of the death penalty back on the table for the trio. It was announced in a memorandum on Friday.

On Wednesday, the Department of Defense reached a plea deal with Mohammed, Ali Abdul Aziz Ali, and Ramzi Bin al Shibh, three men accused of planning the attacks. The details of the deal weren’t made public.
