CAIRO -- A ballistic missile fired by Yemen's Houthi rebels Saturday killed at least 14 people in a government-held city, including a 5-year-old girl, an official said, as a U.S. envoy to the country accused the rebels of failing to try to reach peace in the war-wrecked nation.
The missile hit a gas station in the Rawdha neighborhood in the central city of Marib, said Ali al-Ghulisi, the provincial governor's press secretary. All the dead were civilians, he said.
Dozens of people were wounded in the attack, he added. There was no immediate comment from the Houthis.
The government-run SABA news agency reported that the rebels also fired an explosive-laden drone shortly after the missile attack. It said the drone destroyed two ambulances that had rushed to the area.
The attack came just a day after U.S. special envoy for Yemen Tim Lenderking lashed out at the rebels, accusing them of failing to try to reach an urgently needed cease-fire. He said the Iranian-backed Houthis bear the major responsibility for refusing to engage meaningfully and to take steps to "resolve a nearly seven-years conflict that has brought unimaginable suffering to the Yemeni people."
Yemen has been embroiled in a civil war since 2014, when the Iranian-backed Houthis swept across much of the north and seized the capital, Sanaa, forcing the internationally recognized government into exile.
A Saudi-led coalition entered the war the next year on the side of the government. The war has killed more than 130,000 people and spawned the world's worst humanitarian crisis.
Lenderking's remarks came in a statement late Friday by the State Department after his return from a Mideast diplomatic mission on Yemen that took him to Saudi Arabia, Oman, the United Arab Emirates and Jordan.
He also criticized the Houthis' renewed offensive on the oil-rich Marib province, an anti-Houthi stronghold held by the internationally recognized government that is crucial to the country's energy supplies.
The ongoing Marib attack, which began in February amid an international and regional diplomatic push to end the conflict, has left the rebels "increasingly isolated," Lenderking said.
The State Department said Lenderking coordinated his efforts closely with U.N. special envoy for Yemen Martin Griffiths, who held video talks last week with the Houthis' religious and military leader, Abdel-Malek al-Houthi.
Griffiths expressed frustration that his efforts to achieve a cease-fire have been derailed by warring parties seeking gains on the battlefield.
He urged the sides to seize the "considerable regional and international support" for the U.N. peace plan.
Lenderking's rebuke to the Houthis came as the U.N. Security Council criticized the rebels for delaying a technical assessment of an oil tanker moored off the country's coast loaded with more than 1 million barrels of crude oil.
An Omani delegation, meanwhile, arrived in Sanaa for talks with rebel leaders that aim to advance the peace process, said Mohammed Abdul-Salam, the chief Houthi negotiator.
U.S. Secretary of State Antony Blinken spoke by phone Friday with Omani Foreign Minister Badr bin Hamad bin Hamoud al-Busaidi.
Blinken reiterated the need for "an immediate, comprehensive ceasefire to help bring the war in Yemen and the humanitarian suffering of the Yemeni people to an end," according to the State Department.
