Mauritanian diplomat Ismail Ould Cheikh Ahmed seeks to bring Yemen's feuding armed groups toward a political accord that could end more than six weeks of ground battles and Saudi-led bombing.

Yemen has been since March 26 under brutal aggression by Saudi-US coalition.

Thousands have been martyred and injured in the attack, with the vast majority of them are civilians.

Riyadh launched the attack on Yemen in a bid to restore power to Yemen’s fugitive president Abd Rabbuh Mansour Hadi, a close ally to Saudi emirs.

On April 21, Saudi Arabia declared the end of the aggression, dubbed “Decisive Strom,” and the start of another campaign called “Restoring Hope.” The Saudi-led warplanes are still conducting airstrikes on several areas across Yemen.
