The attack comes as Omani delegation arrives for mediating peace talks between the Yemeni government and Houthi rebels.
At least 17 people, including a five-year-old girl, have been killed after a ballistic missile targeted the Yemeni city of Marib in an attack the government blamed on the Houthi rebels.
The missile hit a petrol station in the Rawdha neighbourhood, said Ali al-Ghulisi, the provincial governor’s press secretary.
Information Minister Moammar al-Eryani said the attack wounded at least five others and all casualties were civilians.
He called on the UN and the US to condemn the attack, saying it amounted to a war crime.
There was no immediate comment from the Houthis.
Yemen has been embroiled in a civil war since 2014, when the Iran-backed Houthis swept across much of the north and seized the capital, Sanaa, forcing the internationally recognised government into exile.
The Saudi-led coalition entered the war the following year on the side of the government.
The war has killed more than 130,000 people and spawned the world’s worst humanitarian crisis.
The government-run SABA news agency reported that the Houthis also launched an explosive-laden drone shortly after the missile attack.
It said the drone destroyed two ambulances that had rushed to the area.
Since February, the Houthi rebels have been attempting to capture Marib to try to complete their control over the northern part of Yemen.
Saturday’s attack came just a day after the US special envoy for Yemen, Tim Lenderking, accused the Houthis of failing to try to reach an urgently needed ceasefire.
Lenderking’s remarks came in a statement late on Friday after his return from a Middle East diplomatic mission on Yemen that took him to Saudi Arabia, Oman, the United Arab Emirates and Jordan.
Omani delegation in Sanaa
An Omani delegation, meanwhile, arrived in Sanaa for talks with Houthi leaders to advance the peace process, according to Mohammed Abdul-Salam, chief Houthi negotiator.
“We arrived in Sanaa accompanied with a delegation from the Omani Sultanate office in an attempt to prompt the process of settling the humanitarian crisis, as well as the peace process as it serves the nation’s interest and the neighbouring countries interests,” Abdul-Salam said.
The visit came after US Secretary of State Antony Blinken spoke by phone on Friday with Omani Foreign Minister Badr bin Hamad bin Hamoud al-Busaidi.
