En amerikansk lærer som har bodd to år i Jemen med familien, ble skutt ned og drept i byen Taiz søndag.
Tjenestemenn trodde det var al Qaida som var på ferde.
The teacher was on his way to work when the gunmen approached his car and opened fire, according to Hamoud al-Sofi, the governor of Taiz, who was reached by phone.
He said that an investigation was under way, and that the information the authorities had so far pointed to a possible involvement by Al Qaeda in Yemen.
“We are all sad in Taiz and we consider this a disaster,” he added.
The teacher had been living in Taiz along with his wife and two children for at least two years, Mr. Sofi said.
According to another Yemeni official, who spoke on the condition of anonymity because the investigation is continuing, the teacher worked for a vocational institute for people with disabilities that was established by the Swedish Free Mission, a charitable organization largely financed by churches.
