Motorcycle-riding gunmen linked to al Qaeda shot and killed an American teacher in the Yemeni city of Taiz Sunday.
A police source said a gunman riding on a motorcycle driven by an accomplice shot a U.S. English language teacher who was also deputy director of the Swedish Institute language school.
A witness describes what happened.
(SOUNDBITE)(Arabic) UNIDENTIFIED WITNESS SAYING:
"Two men were riding on a motorcycle. One of them opened fire at the car and killed a foreign man inside the car."
Officials from the Institute identified the victim as Joel Shrun, who was born in 1983.
The attacks underscore the challenges facing President Abd-Rabbu Mansour Hadi who took office last month after a year of massive protests against his predecessor Ali Abdullah Saleh.
The gunmen, who escaped after the attack, are believed to be linked to al Qaeda. A group affiliated with the militant network claimed responsibility.
