TEHRAN - Iranian security forces killed three people on Monday and arrested four others they suspected of being behind a pipeline blast which halted gas exports to Turkey last week, Iran's student news agency ISNA reported.
Officials in Maku, a city in Iran's West Azerbaijan province, said the militants had crossed the border from Iraq to blow up the pipeline and that at least one was a Turkish citizen.
"'Jamil', a Turkish national and head of this terrorist group, was killed along with two others," Maku governor, Hamid Ahmadian was quoted as saying.
Gas exports to Turkey were briefly halted due to a blast on Friday. The pipeline was swiftly repaired and gas flows were resumed on Saturday.
