Yemen ? Suspected al-Qaida militants opened fire on a convoy of tourists in a remote desert mountain valley Friday, killing two Belgian women and their Yemeni driver. It was the second recent militant attack on foreign tourists in Yemen, the ancestral homeland of Osama bin Laden.

The victims were traveling in a convoy of at least four vehicles through an ancient, ruin-filled desert valley called Wadi Daw’an in Yemen’s eastern Hadramut region when the gunmen attacked, a security official said. Four people were wounded.

Karina Lambert, who survived the attack, said it was carried out by four gunmen hiding behind a pickup truck parked by the road.

At least 10 suspects have been taken into custody and all roads leading to the province have been cut, said the Yemeni official, who spoke on condition of anonymity because he was not authorized to speak to the media.
