Saudi-led air strike has killed at least 30 people in the southern Yemeni port city of Aden.
It is yet unsure how many of the dead were civilians or Houthi rebels who caught the capital, Sanaa last year, and insisted on President Abdrabbuh Mansour Hadi being banished.
Up to 3,000 people have been killed since the Saudi-led attacks began in March, according to UN.
Witnesses said that the latest strike hit a marketplace in Fayoush, a suburb of Aden.
One of the residents said “There was blood of people mixed with that of the sheep and other livestock at the market.”
Efforts are going on to conclude a humanitarian truce that would run through a major Muslim festival “Eid al-Fitr” this month.
Both the Houthis and the Yemeni government have informed a readiness for observing a truce.
The UN has proclaimed its highest emergency level in the country, which more than 80% of Yemeni population demand aid.
