A bomb explosion hit vehicles carrying South Korean diplomats and civilians in the Yemeni capital, Sanna, Wednesday, but no one was hurt, South Korean foreign ministry said Wednesday.

The attacked South Koreans included the government officials dispatched there to investigate the prior attack on South Korean tourists in Yemen's eastern city of Shibam earlier this week, diplomats at the South Korean embassy, and the families of the victims of the Shibam terror, the ministry said.

The Shibam attack, which the Yemeni government announced to be Al-Qaida's terror, killed four South Korean tourists and wounded three others of the same group tour.

"A bomb exploded between the convoy of three vehicles carrying the South Koreans and a guard motorcycle, abruptly about 10 minutes before the vehicles arrived at an airport in Sanna," a ministry official told reporters.

"Windows of the car in the front were broken, but no one was hurt fortunately," he added.

"We are trying to determine whether it targeted South Korean officials or not," he explained, saying that the government does not rule out the possibility that the attacker might have believed the convoy involved high-profile Yemeni government officials.

A Yemeni official said that it was a suicide bombing and that the attacker died at the scene of the explosion.
