According to sources close to Houthi negotiators, who spoke anonymously due to restrictions on speaking to media, Ismail Ould Cheikh Ahmed proposed the ceasefire at a meeting held this week in Omani capital Muscat.

An earlier ceasefire applied in April collapsed after Kuwait-hosted peace talks fell through in August.

Delegations representing the Houthis and Saleh, however, conditioned the new ceasefire on a halt to all military activities in Yemen by a Saudi-led, anti-Houthi Arab coalition.

Yemen has remained in a state of civil war since late 2014, when the Houthis overran capital Sanaa and other parts of the country, forcing President Abd Rabbuh Mansour Hadi and his Saudi-backed government to temporarily flee to Riyadh. 

In March of last year, Saudi Arabia and its Arab allies launched a massive military campaign in Yemen aimed at reversing Houthi gains and restoring Hadi’s embattled government. 

Backed by Saudi-led airstrikes, pro-Hadi forces have since managed to reclaim large swathes of the country’s south -- including Aden -- but have failed to retake Sanaa and other strategic areas.

UN-brokered peace talks held earlier this year in Kuwait failed to achieve any tangible breakthroughs.

In a related development this week, two Iranian fishing ships entered Yemeni territorial waters, Fahd Kafain, Yemen’s minister of fisheries, alleged.

"Two Iranian ships entered Yemeni waters -- for the second time in recent months -- in a provocative manner," Kafain said on his personal Facebook page.

"The two vessels came within less than five miles of the islands of Abd al-Kuri and Sahma southwest of the Socotra Archipelago in the Indian Ocean," he added, without giving a specific date for the alleged incident.

The minister went on to describe the alleged maritime intrusion as "a blatant violation of Yemeni territorial waters, a clear violation of international law and an act of illegal fishing".

Anadolu Agency was unable to obtain immediate comment from the Iranian authorities regarding the minister’s assertions.
