Two Japanese women taken hostage by Yemeni tribesmen have been freed unharmed, according to the Japanese foreign ministry.
The Japanese embassy said on Thursday that it had received notice from Yemeni authorities that the women, kidnapped while on their way to a tourist site, were now safe.
The Japanese ministry said an embassy official had spoken with the women by telephone to confirm their identities and safety.
The Yemeni official said the kidnappers had been demanding the release of Malek bin Hassan bin Muaili, a member of their tribe, by the central government.
He had been detained on suspicion of involvement in an April 16 bombing which killed three policemen in Marib.
It was not immediately clear if he had been released.
