The ceasefire came after several humanitarian organizations criticized the Saudi regime for blocking air, land and sea routes into Yemen.
In one instance of such attempts, fighter jets of Saudi Arabian-led coalition bombed the runway of Sana'a airport on April 28 to prevent an Iranian plane carrying aid cargos from landing in the Yemeni capital.
Yemen has long suffered from desperate poverty, political dysfunction and al-Qaeda's most lethal branch.
On March 26, Saudi Arabia and some of its Arab allies began to militarily interfere in Yemen's internal affairs by launching deadly air strikes against the Houthi Ansarullah movement in an attempt to restore power to the fugitive former President Abd Rabbuh Mansour Hadi, a close ally of Riyadh.
The Saudi-led coalition announced on April 21 that its military operation "Decisive Storm" has ended, but hours later, air strikes and ground fighting resumed.
According to the spokesman of the Yemeni Army, the Saudi-led war on the Arab country has killed 2,051 people, most of them civilians.
