The UN special envoy for Yemen urged the warring parties in the Arab country to extend a temporary ceasefire for at least another renewable 72 hours. The current 72-hour truce expired yesterday. There was no immediate word on whether the combatants would agree to extend the cease-fire. <br/><br/>In a statement released by the UN spokesperson Ismail Ould Cheikh Ahmed, it said the ceasefire was largely holding despite reported violations from both sides in several areas. He noted that the ceasefire over the last days had enabled UN personnel to deliver food and humanitarian supplies to several areas that were previously inaccessible. Ahmed expressed the hope that if the warring parties agree to extend the cease-fire it will lead to a permanent and lasting end to the conflict.
