The UN office in Geneva said the special envoy for Yemen, Ismail Ould Cheikh Ahmed, will hold a press conference Sunday on the topic, AP reported.
The peace talks between pro-Hadi militias and Houthi revolutionary forces began Tuesday in the Swiss village of Macolin.
Fierce fighting and airstrikes by Saudi warplanes repeatedly violated the seven-day UN-brokered ceasefire.
On Thursday, militants loyal to Yemen’s fugitive former president Abd Rabbuh Mansur Hadi captured a major northern town in Yemen in blatant contravention of the truce, which came into effect on December 14.
Back in May, Yemen consented to a truce proposed by Saudi Arabia, but the five-day humanitarian ceasefire was soon disrupted by the monarchy's airstrikes.
Since March 26, Saudi Arabia and some of its Arab allies, including the United Arab Emirates, have been launching deadly airstrikes against the impoverished Arab country in an attempt to restore power to the fugitive former President Abd Rabbuh Mansour Hadi, a close ally of Riyadh.
According to Yemeni sources, some 7,500 people have been killed in the Saudi-led aggressions so far.
