A US court has temporarily blocked Khalid Sheikh Mohammed from making a guilty plea deal that would have spared him the death penalty. The Biden administration intervened after months of attempts to block the deal, which would have allowed Mohammed and two co-defendants to plead guilty to 2,976 murder charges in exchange for life sentences. The appeals court's decision is temporary, with a final ruling expected after further arguments. Families of 9/11 victims are divided on the issue, with some wanting the plea deal and others advocating for a full trial.
