Sky News quoted Special Representative of UN's Secretary-General Ismail Ould al-Sheikh Ahmed as saying that the humanitarian ceasefire will be announced in the next 24 hours.
Sheikh Ahmed, who has held talks with different sides of the ongoing war in Yemen, will likely call the ceasefire before leaving the Arab country, Al Mayadeen TV reported.
The truce would come over 100 days after Saudi Arabia and some of its Arab allies began to launch deadly air strikes against the Houthi Ansarullah movement in an attempt to restore power to the fugitive former President Abd Rabbuh Mansour Hadi, a close ally of Riyadh.
According to a civil coalition monitoring Saudi Arabia's crimes, more than 3000 people, including 722 children and 532 women, have been killed during Saudi-led military strikes on the Arab country. More than 8,000 others have been also injured in the attacks, including 581 women and 766 children.
The Saudi-led aerial strikes have targeted 61 hospitals and 13 ambulances.
Yemen's health ministry, meanwhile, says health conditions have deteriorated in the country, saying some 20,000 people have caught malaria, with some infected children having died due to lack of medication.
