The family members of Noori have said that his dead body was found in Lashkargah city after he went missing around 10 am local time.
Provincial governor for Helmand province, Mohammad Naeem, said investigations have been launched regarding the death of the local journalist.
Noori was originally a resident of eastern Laghman province and used to work with the New York Times during the past two years.
Abdul Salam Zahid, head of the local radio station “Bost” in Helmand said Noori was being threatened by anti-government armed militant groups during the recent months.
In the meantime, a brother of Noor Ahmad Noori has said that he had left working for New York Times recently after he was receiving threats from the militants in Helmand province.
Helmand is among the most volatile provinces in southern Afghanistan where Taliban militants are openly operating in its various districts.
Several journalists including Abdul Samad Rouhani who was working for BBC and Ajmal Naqshbandi along with a number of other local journalists were killed by Taliban militants during the past 10 years in Helmand province.
