The Iraqi Kurdistan region’s fractious internal politics are threatening to derail the construction of a pipeline that could enable future natural gas exports to Turkey — a potential setback for Europe as it seeks to reduce dependence on Russian energy following the invasion of Ukraine.

The Kurdistan Regional Government (KRG) has already signed a contract with the Iraqi Kurdish company KAR Group to expand and extend an existing domestic gas pipeline network, but work on the ground can only move forward with the permission of the Patriotic Union of Kurdistan (PUK) — the political party that controls the eastern half of Iraqi Kurdistan, including the semi-autonomous region’s most important gas fields.
