The Libyan government says its forces have arrested a senior Islamic State group figure.
Embarak al-Khazimi was captured at Bani Walid, south-east of the capital, Tripoli.
Prime Minister Abdul Hamid Dbeibah said the arrest was a great success that would make it possible to gather information on IS.
Three years ago, the group was driven out of the last bit of territory it held in Libya.
Its members are now in hiding, or holed up in the desert, but they remain a threat to the country and the region.
