Iran’s President Hassan Rouhani said Wednesday Yemenis targeted Saudi oil facilities as a “warning” about a possible wider war in response to the kingdom’s US-backed intervention in their conflict-ravaged country. “Learn lessons from this warning and consider that there could be a war in the region,” he said, in a likely address to the rulers of Saudi Arabia which has spent billions of dollars on US weapons. Yemen’s Iran-aligned Huthi rebels claimed responsibility for the strikes but a US official said Tuesday that the administration of President Donald Trump concluded the attacks involved cruise missiles from Iran.
