The Iran war has caused a significant oil supply disruption, according to energy expert Francesco Sassi. This may lead to increased energy costs in Europe as national governments take unilateral action to secure energy supplies.

Speaking with FRANCE 24's Sharon Gaffney, Francesco Sassi, Assistant Professor at the University of Oslo and energy geopolitics expert, says that the Iran war has provoked "the largest oil supply disruption in history" adding that "what is really concerning is that national governments will start to unilaterally take action, subsidising energy consumption or act to secure energy supplies, and this will inevitably increase the cost of natural gas and oil in Europe".
