In a statement to the Yemeni news agency, Saba, Fatah said that the Houthis had intervened in relief and humanitarian efforts in Sanaa and the provinces under their control.
He also said that the Houthi rebels were behind the explosion that damaged a Turkish vessel in Yemen's Saleef port, which is just north of the Houthi-controlled port of Hodeidah on the Red Sea.
"It has sharpened the focus in our mind with this happening".
The Houthis are fighting a Saudi-led coalition in Yemen's years-long civil war.
The rebel group has fired a number of ballistic missiles into neighboring Saudi Arabia in recent months.

Neither the Houthis nor a coalition spokesman could immediately be reached for comment.
The Saudi-led coalition says one of the main justifications for its intervention is to protect shipping routes through the narrow Bab al-Mandab waterway, which connects the Red Sea with the Gulf of Aden and the Arabian Sea, through which almost 4 million barrels of oil are shipped daily to Europe, the United states and Asia plus commercial goods.
The U.S. has provided logistical support and intelligence to the Saudi-led coalition conducting strikes in Yemen since the campaign began in 2015. They were described as being deployed by the Houthi movement to target the tanker.
He said that the militias forged the names of those entitled to relief and deceived global organizations in order to seize the aid, use it for the war effort and sell it on the black market. "So, the attacks will continue", Mobbs said.
