Tourists killed in Yemen explosion

Four tourists and a Yemeni man have been killed in an explosion at a tourist site in Yemen, a security official has said.

The tourists were believed to have been from South Korea, the official said on Sunday.

Authorities were investigating what caused the blast, which also injured five people, at an archaeological site in the southern province of Hadramut.

The explosion happened as the tourists passed a vehicle, one official told the Reuters news agency.

"Preliminary information indicates there may have been a suicide attack, but this has not yet been confirmed," an official said on Sunday.

"Maybe it was a terrorist attack, but it could also be remnants of dynamite from a mine going off," another official said.

No group has claimed responsibility for the blast in the town of Shibam and security sources have not accused any group.

Shibam is a Unesco world heritage site and dubbed the "Manhattan of the Desert" because of its high-rise mud-brick buildings.
