The authorities in Kuwait say they have thwarted three planned attacks by so-called Islamic State, including a plot to blow up a Shia mosque.
An interior ministry statement said security agencies had arrested five Kuwaitis and an Asian in a series of raids inside Kuwait and abroad.
Those held include a woman and her son, who were living between Syria and Iraq.
Last year, a Saudi suicide bomber killed 27 people when he blew himself up inside a Shia mosque in Kuwait City.
At least one man has been sentenced to death in connection with the attack, which IS said it was behind.
