- The intended target was a Houthi command center, a Saudi official said
- Coalition officials express "deep sorrow" for deaths
The strike killed 16 people, including seven children, Yemen's rebel-controlled health ministry said Friday.
The attack, which flattened two buildings in Sanaa's southern district of Faj Attan, comes amid escalating violence in the war-torn country.
A Saudi-led coalition spokesman expressed "deep sorrow for this unintentional accident and for the collateral damage among civilians."
The intended target of the strike was a command-and-control center for Houthi rebels, spokesman Col. Turki al-Malki said, calling it "a legitimate military target."
The facility, al-Maliki said, was intentionally set up in a residential area to turn civilians into human shields.
Saudi Arabia, backed by a coalition of Arab states, launched a military operation in March 2015
