Thousands of Yemenis have marched in the capital Sanaa to protest a Saudi-led coalition airstrike that hit a funeral hall packed with hundreds of mourners, killing over 140 people.
The casualty toll, given by a UN official, also mentioned over 525 wounded in Saturdays attack which was one of the deadliest single attacks of the country's civil war.
The rebel-controlled Health Ministry gave a lower figure, saying that 115 bodies had been counted but that the number will likely rise because "charred remains'' were still being identified.
Of the 600 wounded it tallied, it said many cases were serious and at least 300 would need treatment abroad.
Some of the demonstrators who marched outside the UN building in southern Sanaa on Sunday blamed the organisation for not ending the conflict and urged an independent investigation.
Some protesters brandished automatic weapons and rebel supporters in the crowd called on people from the region to rise up and attack Saudi Arabia.
The Saudi military announced early Sunday it would launch an investigation into "reports about the regrettable and painful bombing'' in Sanaa, without acknowledging that its coalition battling rebels in Yemen is the only force with air power in the conflict.
It is the latest in a string of bombings by the coalition that have struck hospitals, markets and other places where civilians congregate.
