Ambassadors of the group of 18 countries reiterated on Saturday their concern over the actions of Houthi insurgents in Yemen, warning that their moves lead to further divisions and calling on all sides to abide by the efforts aimed at reaching a peaceful solution to the crisis.

“The Group of Ambassadors repeats its concern that actions taken by elements of the General People’s Congress and the Houthis as well as their supporters are making the search for a peaceful solution more difficult by unconstitutional and unilateral actions in Sana’a,” G18 said in a statement.

“These actions only increase the divisions in Yemen and will not address the political, economic, and security problems that are causing such widespread suffering throughout the country.”

The G18 also expressed “concern about the escalation of violence” and reiterated its call on all sides to “immediately implement the cessation of hostilities.”

The ambassadors urged all parties to deal responsibly with the efforts of the U.N. Special Envoy, Ismail Ould Cheikh Ahmed, and to adhere to the references for a peaceful solution; the GCC Initiative and its Implementation Mechanism, the outcomes of the National Dialogue Conference, and relevant Security Council resolutions, including Resolution 2216.
