The United Nations envoy to Yemen, Ismail Ould Cheikh Ahmed, called on a Saudi-led military coalition and the country's warring parties to extend by five more days a ceasefire set to expire on Sunday evening.

The Mauritanian diplomat was speaking at a conference of Yemeni parties in the Saudi capital Riyadh aimed at ending the conflict in Yemen.

For his part, Yemen's Vice President Khaled Bahah said on Sunday his administration favored an extension of a five-day ceasefire expiring in the evening but this would depend on the situation on the ground.

"We need the ceasefire to continue for long, not just for a few days, but it depends on the operation on the ground," Bahah told Reuters in the Saudi capital, Riyadh.

"There is an effort for an extension, but it depends on how it is on the ground. But it's our wish from the government side that we need to extend it," he added.

Yemen has been since March 26 under brutal aggression by Saudi-US coalition.

Thousands have been martyred and injured in the attack, with the vast majority of them are civilians.

Riyadh launched the attack on Yemen in a bid to restore power to Yemen’s fugitive president Abd Rabbuh Mansour Hadi who is a close ally to Saudi Arabia.

On April 21, Saudi Arabia declared the end of the aggression, dubbed “Decisive Strom,” and the start of another campaign called “Restoring Hope.” The Saudi-led warplanes are still conducting airstrikes on several areas across Yemen.
