"Our cash assistance helps families meet their food needs," UNHCR said on Twitter.
The UN organization pointed out that it was able to help feed more than 300,000 Yemenis through the Qatari "Al-Thani Humanitarian Fund," the Middle East Monitor reported.
Since March 2015, Saudi Arabia and some of its Arab allies have been carrying out deadly airstrikes against the Houthi Ansarullah movement in an attempt to restore power to fugitive former president Abd Rabbuh Mansour Hadi, a close ally of Riyadh.
The war has killed tens of thousands of people, mostly civilians, and resulted in what the UN has described as the world's worst humanitarian crisis.
Some 3.3 million people have been displaced from their homes and 24 million, or more than 80 percent of the population, are in need of aid, according to the UN.
