Yemeni officials say three Italian women kidnapped and freed by tribesmen have returned to their captors to press for the release of two Italian men still in custody.
Authorities initially said the women had been freed, and authorities were negotiating to gain the release of the remaining two hostages.
But an official later said that the women returned to the kidnappers, saying they would remain until all five were freed.
Officials said the Italians had been seized by members of the al-Zaida tribe, who urged the government to release eight jailed tribesmen.
On Saturday, five German tourists were released after being held for three days by Yemeni tribesmen demanding the release of jailed tribe members.
