The UN postponed talks on Yemen which were scheduled for May 28 in Geneva as the government insists it will not participate in talks except after the Houthi militant group adheres to UN resolutions.
Agencies quoted the UN envoy to Yemen Ismail Ould Cheikh as saying the talks have been postponed indefinitely.
Two days ago, president Abd Rabbuh Mansour Hadi urged the UN to take action so that the Houthi group respects and implements all UN resolutions especially the resolution No. 2216 on the transition process.
The resolution No.2216 called on the Houthi militants to cede power, give up weapons and withdraw from cities they seized after ousting Hadi and the transition government.
Meanwhile, a UN official revealed on Sunday that the GCC, the Arab League, the Organization of the Islamic Conference, the five permanent members in the Security Council, Germany, Japan and the European Union will be invited to the Geneva talks between Yemeni factions.
The talks come amid escalating post-Houthi takeover violence that has led to a fast aggravating humanitarian crisis.
According to the UN, around 68% of the Yemeni population are in dire need for aid.
At least 5 million people of those affected by recent violence are starving and need emergency food aid, the UN says.
Moreover, international organizations have warned the healthcare system is on verge of collapse due to lack of fuel, persistent power outages and lack of life-saving medicines.
A blockade on all Yemeni ports which was part of a Saudi-led military operation against the Houthis was to blame for the worst lacks of supplies in the country.
The UN is appealing to the Arab coalition and the Houthi group to agree and then respect an extension of a short humanitarian ceasefire which ran during May 12-17.
