ANKARA, Turkey (AP) — An explosion in Turkey has forced authorities to shut down a pipeline carrying oil from Iraq to world markets, an official said Monday, in the second such incident in two weeks. Local media reports said Kurdish rebels had caused the blast.

The explosion occurred late Sunday near the southeastern town of Midyat and damaged the pipeline running from Kirkuk, in northern Iraq, to the Turkish Mediterranean port at Ceyhan, said an official at Turkey’s pipeline company, BOTAS. A second line that runs parallel was not harmed, but has also been shut down temporarily as a precaution, the official said.
