Raid on Biko peace talks

In 2558, a peace conference on Biko was raided by John-117. Many human civilians were killed and the alien ambassadors were escorted off-world by the Spartan.

Prelude
After years of diplomatic work, peace talks were finally scheduled between humanity's Unified Earth Government and former members of the Covenant. The convocation was held in a regional embassy in a densely populated city on Biko in the human Outer Colonies. Richard Sekibo, the revered ambassador of the Outer Colonies, led the conference.

The raid
As the conference was coming to an end, an agreement of peace was close to being reached. Suddenly, rogue Spartan-II John-117 entered the embassy and instantly killed Richard Sekibo's bodyguard. A firefight began, in which nineteen human security guards were killed. John abducted Sekibo and created an escape path through security personnel by killing them. John fled the embassy alongside the alien delegation, which he escorted to safety.

Outside the embassy, an evacuation ship for John was waiting. He boarded the ship, alongside the alien diplomats, and fled the planet. At some point, Sekibo was killed and his corpse was left behind in a field near the embassy on Biko. The next day, local officials discovered a signal beacon that led them to the body of Sekibo.

Aftermath
The event was leaked onto human public networks and news sites by FERO, an unidentified Insurrectionist leader. Some of the people who had become aware of the event accused John-117 of being a traitor, working with the enemy, assassinating a beloved diplomat, and killing civilians. Many people became divided on whether the hero of the Human-Covenant War—the Master Chief—was a traitor or not. Many Inner Colony residents denounced the Master Chief, while Outer Colony residents were becoming increasingly disgruntled.

FERO leaked the event with the intentions of getting the public to feel betrayed by John's apparent disloyalty. Then, she would reveal the Office of Naval Intelligence was responsible for abducting children for the SPARTAN-II program and for ultimately psychologically transforming the Master Chief into a traitor. Meanwhile, a meeting was scheduled between the UEG's senate and ONI to discuss the event, during which a leak of ONI's action in the SPARTAN-II program occurred.

Trivia
The image of John-117 attacking the embassy appears to be a modified still of John during the final cutscene of Forerunner in Halo 4.
