More than 300 police and military personnel have been deployed to Papua New Guinea's Hela province as an operation to end a spate of lawlessness gets underway.
The chief secretary to the national government, Isaac Lupari, said the personnel will march in the provincial capital, Tari, on Monday before being deployed across the province.
He said the operation is necessary because the fighting represents a genuine threat to law and order in the province.
Mr Lupari told the Post Courier newspaper that the operations will be reviewed at the end of February.
An arms moratorium has also been introduced.
