At least 78 people have been killed in a crush at a school in the Yemeni capital Sanaa during the distribution of charity for Ramadan, officials say.
TV footage shows a crowd of people unable to move and many in distress in the Bab al-Yemen area of the city.
Hundreds of people reportedly crowded into the school late on Wednesday to receive donations amounting to about $9 (£7; €8) per person.
The rebel Houthi movement has controlled Sanaa since 2015.
A video posted on social media shows people screaming with dozens of bodies on the ground, some of which are not moving. Other people are seen trying to help.
Two local businessmen who arranged the event had been arrested and an investigation was underway, the interior ministry said.
A spokesman for the ministry blamed the crush on the “random distribution” of funds without coordination with local officials.
Many people were also injured with 13 in critical situation, a health official in Sanaa said.
“Women and children were among the dead,” a Houthi security official told AFP news agency on the condition of anonymity because he was not authorized to speak to journalists.
The Associated Press news agency quoted two eyewitnesses who said Houthi fighters had fired into the air in an attempt at crowd control, apparently striking an electrical wire which resulted in an explosion. This caused panic that led to the crush, they added.
The rebels are said to have then sealed off the school and barred people, including journalists, from approaching.
The Houthis have reportedly agreed to pay $2,000 (£1,600) to each family who lost a relative, while the injured would get around $400 (£322).
