Saudi Ambassador to the US Prince Khalid bin Salman has said that Yemen’s Houthi insurgents are determined to escalate the war in the country. The Houthis’ “latest terrorist attack on a commercial oil tanker in one of the worlds busiest shipping routes is a demonstration of their disregard for international laws,” the diplomat said on his official Twitter account on Thursday. The attack also shows their “determination to escalate the war" and prolong the suffering of the Yemeni people, he tweeted. The ambassador was referring to the Houthi attack on Tuesday on a Saudi oil tanker in international waters west of the Hodeidah port. The targeted tanker was slightly damaged, but able to continue along its course, escorted by an Arab Coalition vessel.
