UN envoy Ismail Ould Cheikh Ahmed arrived in Cairo Thursday morning to discuss the Yemen crisis, Al-Ahram Arabic news website reported.
During the two-day visit, Cheikh Ahmed is expected to hold talks with Egyptian Foreign Minister Sameh Shoukry, Arab League Secretary-General Nabil El-Araby, key members of the Egyptian government, and Yemenis residing in Egypt, diplomatic sources stated.
The talks will focus on the latest developments in Yemen whose situation has escalated to a regional war.
His visit comes after a meeting held in Saudi Arabia with Saudi Foreign Minister Adel Al-Jubeir, senior officials and Yemenis residing in Saudi Arabia to discuss where Yemen is heading.
On Monday, the Saudi-led coalition declared a five-day true in order to allow the delivery of aid. However, Yemen's Houthi rebels launched an attack and did not adhere to the truce.
Yemeni military sources told AFP that the Saudi-led coalition accidentally fired air strikes on the first day of the humanitarian truce at pro-government forces in South Yemen, killing 12.
In a previous statement, Cheikh Ahmed warned that the country is "one step" from famine.
The United Nations says the conflict has uprooted over one million people from their homes.
Last month, the UN declared its highest-level humanitarian emergency in the country, where over 80 percent of the population need assistance.
