The Director of Public Prosecutions (DPP) has appealed against the High Court's decision to overturn 22-year jail terms handed to two men convicted of possessing explosives, bullets and guns believed to have been intended for what could have been Kenya's deadliest terror attack.

In the appeal, Assistant DPP Duncan Ondimu argued that there is a high risk that Alex Shikanda and Musharaf Abdalla will not attend court, given the seriousness of the charges, following High Court Judge Grace Nzioka's ruling that their convictions were erroneous.

Ondimu claimed that Abdalla had previously escaped from custody as the appeal was going on at the High Court.

He added that Abdalla faces a separate case of committing a terrorist act and had at one point detailed an escape plan from Kamiti Maximum Prison.
