Iranian gas flow to Turkey halted after blast-officials
The blast occurred in the area of Dogubayazit, a town in Agri province near the Iranian border, the officials said, on condition of anonymity.
They said damage assessment work had begun and it was not immediately clear when the gas flow will resume or what caused the blast, which occurred around 4 a.m.
The outlawed Kurdistan Workers Party (PKK) has claimed responsibility for repeated attacks on pipelines in Turkey in its 28-year-old armed campaign against the Turkish state which has claimed more than 40,000 lives.
Flows have also been halted several times on the Kirkuk-Ceyhan pipeline carrying crude oil from Iraq to Turkey in recent months due to suspected sabotage blamed on the PKK.
