Context from the sources
Mohammed is accused of developing and directing the plot that involved hijacked planes striking New York’s World Trade Center and the Pentagon; another plane crashed in Pennsylvania on Sept. 11, 2001. [1][2]
Relatives of Sept. 11 victims have been divided over the plea agreements: some favor a trial, while others view a plea as the best prospect for concluding the case. [2]

Questions answered by the reporting
What this could mean for you

For victims’ families, the ruling means the case remains on a trial track that could extend the proceedings, while the outcome and timing of a 2028 trial remain subject to further litigation and court action.
Possible consequences, not a forecast. Their relevance depends on your location and the conditions above.
