Yemen's Revolution Supreme Council on Sunday said it held the Saudi-led Arab coalition responsible for the country's economic and humanitarian crises, calling for a fact-finding committee to investigate the coalition's activities in Yemen.

Iran PressMiddle East: In a post on Twitter, the Head of the Yemeni Revolution Supreme Council Mohammad Ali al-Houthi accused the coalition of imposing royalties on the Yemenis in return for allowing the entry of basic material, adding that the coalition has seized "oil derivatives in order to double its bill for the citizen, rejected the United Nations permits to allow their entry, plundered oil and wealth and undermined the currency."

"We call for a fact-finding team," he said without further details.

There was no immediate comment from the coalition.

Saudi Arabia, with the support of the United States, the United Arab Emirates, and several other countries, has launched a military offensive against Yemen since March 2015 and imposed a land, sea, and air blockade on the country.
