WASHINGTON — Military prosecutors have refiled terrorism and murder charges against the accused mastermind of the Sept. 11, 2001, attacks and four other men under a revamped trial process at Guantanamo Bay, Cuba, the Pentagon said Tuesday.

The charges against Khalid Sheikh Mohammed and the others allege that they were responsible for planning the attacks that sent hijacked commercial airliners slamming into New York’s World Trade Center, the Pentagon and a field in Pennsylvania, killing nearly 3,000 people.

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 other four alleged co-conspirators are: Waleed bin Attash, better known as Khallad, a Yemeni; Ramzi Binalshibh, a Yemeni; Ali Abd al-Aziz Ali of Pakistan and Mustafa Ahmad al-Hawsawi, a Saudi.
