The Kuwait News Agency reported that those facing trial include seven Kuwaitis and 13 "illegal residents" — a reference to Kuwait's "bidoon" community that is made up largely of desert nomads considered stateless by the government.
Also facing trial are five Saudis, three Pakistanis and a fugitive whose nationality is not yet known.
They face a range of charges such as illegally possessing explosives, incitement to violence and joining an extremist group.
