Iran on Sunday resumed shipping natural gas to Turkey, after cutting supplies during a cold snap almost one month ago, CNN-Turk television reported. Iran cut gas supplies at the beginning of this month, despite having promised not to interrupt shipments again after a reduction last year due to another dip in temperatures. The cut last year sparked debate over Turkey's need to reduce energy dependence on Russia and Iran, its two main suppliers. Turkey uses natural gas in industry and to heat homes. After Russia, Iran is Turkey's second-largest supplier of natural gas, now providing around 20 million to 22 million cubic meters per day through a 2,580-kilometer pipeline. Turkey also imports some liquefied natural gas from Nigeria and Algeria.
