Forces from the Saudi-led coalition struck a market in northern Yemen's Haja province, killing 41 civilians and wounding 75, health officials told Reuters.
Three separate air raids hit the market, according to health officials, in a violent conflict that saw Saudi Arabia's intervention after Houthi militias ousted a pro-Saudi president, who then fled to Saudi Arabia to request military aid.
The conflict in Yemen initially came to a partial pause on Tuesday, was preceded by a Russian withdrawal from Syria, following a peace deal which ended much of the fighting between the Syrian government and rebels. The deal's structure, largely accomplished through Russian diplomatic and military efforts, was also appealed to by the United States in talks over Yemen.
"We both agree that it would be desirable to see if we can find a similar approach, as we did in Syria, to try to get a ceasefire," US Secretary of State John Kerry said in a meeting with Saudi Arabian officials on Saturday.
"You accuse us of fomenting sectarian strife in Syria, Yemen and Iraq. You add insult to injury by telling us to share our world with Iran, a country that you describe as a supporter of terrorism and which you promised our king to counter its 'destabilizing activities'," senior Saudi royal Prince Turki al-Faisal wrote in an editorial published across Saudi media.
Al-Faisal noted that the Saudis still consider Americans an ally, but the message was unique in its distribution and anger, practically unparalleled in previous squabbles over regional policy, which could mean continued defiance of a previously established course toward a drawdown of hostilities between Houthi militias and Saudi-backed forces in Yemen.
