“The blood of my father will be hell ringing in the ears of Iran,” he added. There was no immediate confirmation of the TV report.
Ahmed Ali Saleh had military training in the United States and once led Yemen’s Republican Guard. He later became his country’s ambassador to the United Arab Emirates.
But when the Emirates joined with the Saudis two years ago in attacking the Houthis, he was placed under house arrest. His apparent emergence on Tuesday suggested to some analysts that he was being positioned to take over from his father as a focus of opposition to the Houthis.
The death of Mr. Saleh ended the tumultuous career of a wily strongman who combined charisma, duplicity and brute force to remain a giant in the politics of his impoverished country for decades.
Mass protests in 2011 during the Arab Spring forced him to stand down as president, but he confounded those who thought he might retire quietly by returning to the country to rally his followers and forge an improbable alignment with the Houthis, before breaking with them just days before his death.
His killing signaled a turning point in the country’s war by shattering the alliance between his loyalists and the Houthis, who had taken over the capital, prompting a punishing bombing campaign by Saudi Arabia and its allies.
The political fracturing could make it harder for the parties to negotiate an end to the conflict, analysts said, while renewed fighting in Sana could worsen the humanitarian crisis afflicting Yemen.
Seven million Yemenis — nearly a third of the population — are at risk of starving, the United Nations has said. Millions more need emergency food aid.
