No group claimed responsibility for the incident nor the official authorities have commented on it yet. However, a Yemeni security official confirmed the abduction, but he declined to give further details. Foreigners are frequently kidnapped in Yemen by al-Qaida militants or tribesmen who asked for ransom or for the exchange for their jailed fellows. Most of the kidnapped have been freed unharmed. Last month, a Dutch couple and two South Africans were kidnapped in Sanaa and the central province of Taiz and the Yemeni government is still searching for the four people.
