They stipulated that they stop targeting ships... American-British intervention stops any dialogue with the Houthis

Informed political sources said that the dialogues that were scheduled to be held in the Kingdom of Saudi Arabia between the Yemeni parties have been postponed to another time as a result of American-British intervention by imposing strict conditions for the Houthis to stop their attack on ships in the Red Sea and the Gulf of Aden in exchange for returning to the road map path.
The UN envoy to Yemen is expected to arrive in Riyadh tomorrow.
