Saudi Arabia’s deputy consul in the southern Yemeni city of Aden has been kidnapped outside his home.
Police in the city’s Mansoura district said gunmen abducted Abdullah al-Khalidi as he was about to get into his car, escaping in another vehicle.
A security operation is now under way in the city in an effort to find him.
Aden is the city closest to Yemen’s Abyan province where government forces have been struggling to contain militant groups linked to al Qaeda.
In the past year these groups have consolidated their control over several towns and villages in the region, including Abyan’s capital Zinjibar.
Kidnapping is common in Yemen, with captives often being held as negotiating tools in disputes between rival tribes or armed groups.
Earlier on Wednesday Saudi Arabia announced it would provide Yemen with all its petroleum needs for two months.
The official news agency Saba announced the deal in its report of a meeting between King Abdullah and the Yemeni president Abd-Rabbu Mansour Hadi.
Attacks by armed groups on pipelines have hit Yemen’s small oil industry hard, with both domestic and export production badly affected.
