"The Secretary-General condemns the attack on an event hall in Sana’a where hundreds of people were gathered for a funeral ceremony,” the statement read.

“Initial reports indicate that the attack, said to have been airstrikes by the Coalition, killed over 140 people and injured hundreds of others… The Secretary-General notes that any deliberate attack against civilians is utterly unacceptable and calls for a prompt and impartial investigation of this incident. Those responsible for the attack must be brought to justice," it added.

According to the UN estimates, the attack claimed over 140 lives and left more than 534 people wounded. 

Yemen has been engulfed in a military conflict between forces allied with fugitive former Yemeni President Abd Rabbuh Mansour Hadi and Houthis since 2014. Since March 2015, the Saudi-led coalition of mostly Persian Gulf countries has been carrying out airstrikes against the Houthis at the request of Hadi.
