Saudi-led coalition warplanes yesterday struck a second home owned by the son of former Yemeni President Ali Abdullah Saleh in the capital Sanaa.
Plumes of smoke were seen billowing from Ahmed Saleh's residence in western Sanaa following the airstrike, according to eyewitnesses.
It remains unclear whether Ahmed, a former commander of Yemen's Republican Guard, was inside the building at the time of the attack.
Last month, coalition warplanes struck Ahmed's home in southern Sanaa.
Fractious Yemen has remained in turmoil since last September, when the Houthis overran capital Sanaa, from which they have sought to extend their influence to other parts of the country.
On 25 March, Saudi Arabia and its Arab allies began an extensive military campaign targeting Houthi positions across Yemen.
Riyadh says its anti-Houthi campaign comes in response to appeals by embattled Yemeni President Abd Rabbuh Mansour Hadi – currently in Riyadh – for military intervention against the Shia group.
The Houthis, for their part, denounce the offensive as unwarranted "Saudi-American aggression" against Yemen.
