The attack blasted a building that was hosting the funeral for the father of interior minister of Yemen and rebel Houthi loyalist Jalal al-Ruwaishan.
Yemen's acting health minister Ghazi Ismail described the incident as "barbaric air attacks against civilians and civilian targets."
The Saudi-led coalition has denied carrying out the attack.
Yemen has become unstable since a 2011 uprising which led to the end of the 33-year rule of President Ali Abdullah Saleh.
In 2014, the Houthis seized governmental control of Sanaa, leading to the downfall of the Saudi Arabian-backed Abd Rabbuh Mansur Hadi. The Houthis are a socio-political group that grew out of north Yemen in the 1990s in opposition to oppression of the then central government.
A coalition of forces led by Saudi Arabia attacked the Houthis on March 26, 2015 to restore Hadi to power. The country has been in civil war ever since, with about 10,000 Yemenis killed, 3,799 civilians, and three million people displaced from their homes.
