A coalition led by Saudi Arabia has promised to investigate an air raid in Yemen that killed more than 140 mourners.
Iran-backed Houthi militans blamed the coalition for the attack on a funeral hall in the capital Sanaa in which more than 500 were also wounded.
The United States termed it “deeply disturbed” and said it would review its support for the coalition in the Yemen conflict.
After initially denying any responsibility, the coalition said it was ready to launch a probe into the “regrettable and painful” strike, which a UN official said also wounded more than 525 people.
“The coalition will immediately investigate this case along with Joint Incidents Assessment Team in Yemen and experts from the United States who participated in previous investigations,” it said in a statement carried by the Saudi Press Agency.
“The coalition is also willing to provide the investigation team with any data and information related to its military operations today, at the incident’s location and the surrounding areas,” it said.
“The result of the investigation should be announced as soon as it’s completed.”
The UN said aid workers were “shocked and outraged” by the attack on the community hall, where hundreds had gathered to mourn the death of the father of rebel interior minister Jalal al Rowaishan.
It is not clear if Mr Rowaishan or other senior rebel figures were in the building at the time, although Sanaa’s mayor Abdel Qader Hilal was reportedly among those killed.
“We are deeply disturbed by reports of today’s airstrike on a funeral hall in Yemen, which, if confirmed, would continue the troubling series of attacks striking Yemeni civilians,” White House National Security Council spokesman Ned Price said in a statement.
“In light of this and other recent incidents, we have initiated an immediate review of our already significantly reduced support to the Saudi-led coalition and are prepared to adjust our support so as to better align with US principles, values and interests.”
Mr Price stressed that “US security cooperation with Saudi Arabia is not a blank cheque”, and called on all sides to implement an “immediate” ceasefire.
