In a Tuesday tweet, Mohamed Ali al-Houthi, head of the Supreme Revolutionary Commission, reiterated calls for a “political solution” to the almost four-year-old conflict.

“Our initiative would include instructions from Yemeni official parties to halt all military and naval operations for a specified, renewable period,” he said.

Al-Houthi stressed the importance that the Saudi-led coalition's leadership takes a similar step "if they really want peace for the Yemeni people."

The Yemeni people have suffered and still from the humanitarian crisis classified as the worst in the world, as a result of the siege and the aggression, he added.

"The initiative comes with the aim of preserving the Yemeni bloods and in response to the regional and international moves and efforts aiming to bring peace," al-Houthi said.

He called for the official Yemeni authorities to order the cessation of military operations in all fonts for a limited period that can be extended if the coalition leadership takes the same step.

Iran and European powers have made some progress in talks to end the conflict in Yemen as Tehran has shown itself willing to push for a ceasefire and ease the humanitarian crisis there, according to officials on both sides.

Earlier this month, UN envoy to Yemen Martin Griffiths proposed a plan by which the Houthis would pull out of Al-Hudaydah after which Yemeni police and UN observers would fill the vacuum.

The Yemeni crisis escalated in 2015 when Saudi Arabia and its Arab allies launched a massive air campaign on Yemeni people.

The violence has devastated Yemen’s infrastructure, including health and sanitation systems, prompting the UN to describe the situation as “one of the worst humanitarian disasters of modern times”.
