The 27-year-old, who was studying engineering, died hours after arriving at the Republic Hospital, the officials said.
According to witnesses, two people, one of whom later died, were wounded in the clashes in Al-Saada neighbourhood that broke out on Friday when security forces tried to disperse a protest by members of the Southern Movement.
Southern Movement members want either independence or increased autonomy for Yemen's south, which was independent from the 1967 British withdrawal until it united with the north in 1990.
The region, where many residents complain of discrimination by the Sanaa government in the distribution of resources, seceded four years later, sparking a short-lived civil war that ended with the south overrun by northern troops.
Sources in the Southern Movement said that security forces arrested eight demonstrators on Friday in Al-Saada, and denied that the movement's supporters protesting in Aden were armed.
