Iran has halved the volume of natural gas flows to Turkey, citing an increase in domestic consumption due to severe winter weather, Turkish newspaper Milliyet reported on Wednesday.

It said the daily gas flow of some 28-30 million cubic meters had fallen to around 14-15 million cubic meters as a part of the move.

Iran must supply Turkey with a maximum 10 billion cubic meters of natural gas a year under a 25-year deal signed in 1996.
