Four tourists believed to be South Korean and a Yemeni man were killed in an explosion at a tourist site in Yemen, a Yemeni security official said on Sunday. The official said authorities were investigating the incident in the city of Shibam in the southern province of Hadramout and trying to identify those behind it.
The explosion occurred as the tourists visited the city dubbed the Manhattan of the Desert, which boasts the world's oldest skyscrapers dating back to the 16th century, the official told Reuters.
Asked if the explosion was an attack, the official said: "Maybe it was a terrorist attack, but it could also be remnants of dynamite from a mine going off."
