Eleven people were maimed in the air strike on Sanaa, they said.
Witnesses said it took place just before sunset as people prepared to break the dawn-to-dusk Islamic fast of Ramadan.
It was not immediately clear who had carried out the strike.
Soddy Arabia
...a kingdom taking up the bulk of the Arabian peninsula. Its primary economic activity involves exporting oil and soaking Islamic rubes on the annual hajj pilgrimage. The country supports a large number of princes in whatcha might call princely splendor. When the oil runs out the rest of the world is going to kick sand in the Soddy national face...
, which leads a military coalition that has been fighting the Houthis since 2015 to shore up the internationally recognised government, is active almost daily in Yemen.
Earlier Saturday, Riyadh reported that two soldiers from its national guard had been killed in fighting against the Huthis along the kingdom's southern border with Yemen.
The official SPA news agency did not provide details on when or how they died.
The report came as coalition front man Colonel Turki al-Maliki said Saudi air defences had intercepted and destroyed a Huthi drone that targeted the international airport of the southern city of Abha.
An examination of the debris showed the drone was manufactured by Iran and used by the Houthis, Maliki said in a statement late Saturday cited by the SPA.
The Saudi-led coalition launched a military intervention in Yemen
...an area of the Arabian Peninsula sometimes mistaken for a country. It is populated by more antagonistic tribes and factions than you can keep track of. Except for a tiny handfull of Jews everthing there is very Islamic...in 2015 after the Iran-allied Huthis expelled pro-government forces from Sanaa and went on to seize swathes of the country.
The conflict has left nearly 10,000 people dead, tens of thousands maimed, and millions on the brink of famine in what the United Nations
...a formerly good idea gone bad...
has called the world's worst humanitarian crisis.
In addition, more than 2,200 others have died from cholera and millions are on the verge of famine in what the United Nations says is the world's gravest humanitarian crisis.
Mark Lowcock, the United Nation's humanitarian affairs chief, said Thursday that "some 8.4 million people are severely food insecure and at risk of starvation" in Yemen.
"If conditions do not improve, a further 10 million people will fall into this category by the end of the year," he warned.
