A new ceasefire has been reached between al-Houthis and extremist militants fighting in northern Yemen, allowing the Red Cross to evacuate the wounded, the UN envoy said Monday.

"I am happy to say that following intensive efforts... we have reached a ceasefire" in Saada province, Jamal Benomar told reporters.

A Red Cross convoy entered the village of Dammaj and the International Committee of the Red Cross said its teams had evacuated 23 critically wounded people.

"There are still more wounded people in need of treatment, and we hope to be able to come back for them," the ICRC director in Yemen, Cedric Schweizer, said in a statement.

Benomar said Yemeni President Abdrabuh Mansur Hadi had sent a special plane to evacuate the wounded.

"I hope this ceasefire will be permanent, and I hope that efforts will follow to find a solution for the roots of this problem," Benomar said, while also warning the conflict "threatens the security of Yemen".

A statement by al-Houthis accused the extremists of having "transformed the centre of Dammaj into a real barracks for thousands of armed foreigners."

It is worth to mention that Saudi-backed Takfiri extremists carry out attacks against al-Houthis in the north of Yemen.
