The Yemeni Ministry of Defense announced the killing of 20 Houthi militants and wounding others, as a result of an attack by the National Army in the Hilan area of the Sarwah district, west of Marib, as a result of the battles that have been going on for more than 3 days in Marib.
The ministry confirmed that confrontations are still continuing in the governorates of Marib and Al-Jawf, amid the retreat of the Houthis.
Local sources also reported to the island that the Houthis had targeted the city of Marib with a ballistic missile, the second in two days.
While the Houthis expressed their readiness for peace, the United Nations expressed grave concern over their resumption of "hostilities" in Marib.
Yemeni government spokesman Rajeh Badi said that the Houthis wrongly understood the calls of the international community for a ceasefire.
Badi added in a previous interview with Al-Jazeera that the language of the UN envoy to Yemen Martin Griffiths is unclear, and that the Yemeni government will support Marib, and will not allow Iran to impose its conditions on the Yemeni people, as he put it.
On the other hand, Nasreddin Amer, Undersecretary of the Yemeni Ministry of Information of the Houthis, described the military operations in Marib as legitimate and normal.
Amer said in a previous interview with Al-Jazeera that these operations provide a positive atmosphere for political solutions more than the efforts of the UN envoy to Yemen, he said.
For his part, European Union foreign policy and security official Josep Borrell called for a permanent ceasefire in Yemen, and the start of political negotiations between the parties to the conflict.
Borrell said that the war in Yemen has turned into an element of instability in the entire region.
In the same context, the UN envoy to Yemen, Martin Griffiths, expressed his grave concern about the Houthis' resumption of "hostilities" in the Marib governorate.
Griffiths said in a tweet on Twitter that the resumption of these hostilities comes at a time when diplomatic momentum is renewed to end the Yemen war and resume the political process.
The House of Commons discusses the Yemen war
On the other hand, British Secretary of State for Middle East Affairs James Cleverley appeared on Tuesday before the British House of Commons regarding a session on Yemen.
At the session, former leader of the opposition Labor Party, Jeremy Corbyn, asked him whether he accepted the grave humanitarian situation in Yemen.
Corbin said during the interrogation of the British minister that 80% of Yemenis need aid, and that his government has continued its plan over the past five years to sell an estimated billions of pounds of weapons and equipment that Saudi Arabia uses in the Yemen war.
Commenting on this, Cleverley said that his country supports international efforts that support stability in Yemen.
He added, "I spoke to Martin Griffiths on several occasions, and the United Kingdom fully supports his role in trying to bring peace to Yemen. As for the MP's question about what Britain is doing regarding arms sales to Saudi Arabia, I have never heard him criticize Iran for its support of the Houthis and the devastation they inflicted on the Yemeni people."
