LONDON (Reuters) - Oil flow through the Kirkuk pipeline that takes crude from northern Iraq to Ceyhan in Turkey halted on Saturday, the second disruption in less than a month, a shipping source said on Tuesday.
The latest interruption on the pipeline, which normally carries about a quarter of Iraq's oil exports to world markets, followed a bomb attack in late October that halted oil flows until November 2.
"It stopped on the 21st," the source said. The reason for the stoppage was not immediately clear.
One vessel was waiting at Ceyhan to load Kirkuk crude, but there was no loading taking place on Tuesday and only 1.9 million barrels were held in storage tanks at the terminal, the source said.
The pipeline typically pumps about 500,000 barrels per day of oil. The bulk of Iraq's crude oil exports flow through its southern route at Basra.
Sabotage and technical problems kept the Iraq-Turkey route mostly idle until 2007 following the U.S.-led invasion of Iraq in 2003. Flows have increased since 2007, partly due to tighter security.
