Yemen's UN Humanitarian Affairs country director has visited the southwestern Yemeni city of Taiz to be acquainted with people human needs.
This is the first high-level official visit to Taiz since April 2017, said the UN human affairs office, aimed at direct survey of human needs.
"Partners in human field plan to expand operations response to urgent needs of civilians," said the office.
According to sources at Taiz provincial local authority, the visit comes as part of "building capacities of national mechanisms, studying human and HR conditions, and unveiling war crimes committed by Houthi group against humanity and Yemeni people."
Yemen has been racked by an armed conflict that broke out after the Iran-backed Houthis had ousted the internationally recognized government late in 2014.
The conflict escalated after a Saudi-led coalition intervened militarily in the country in March 2015 to reinstate the government of President Hadi, leaving hundreds of thousands killed or injured and 3 million displaced, and pushing the country to the world's worst humanitarian crisis.
Yemen is facing the world's worst humanitarian crisis, according to the UN, with more than two thirds of the 28-million population in need for a type of humanitarian aid and immediate protection, including 8.4 million people unsure how to get next meal, and some 2 million children suffering severe shortage of nutrition.
