Sana'a, Yemen - Yemen on Saturday extradited to Saudi Arabia five Saudi suspects wanted in their country over links to terrorist activities, security sources said.

The sources said the suspects included Abdullah Abdul-Rahman al- Harbi, a leading al-Qaeda suspect who was arrested in southern Yemen on March 14.

Yemen and Saudi Arabia have in recent years swapped dozens of suspects under a security agreement signed by the two countries in 2004.

In February, Yemen extradited to Saudi Arabia Mohammed al-Awfi, an al-Qaeda commander, after he turned himself in to the Yemeni authorities.

Two suspected members of an al-Qaeda cell, including a Saudi national, were killed after police raided a house in Sana'a on January 19.

In August, Yemen said it had detained 30 suspected al-Qaeda members believed to have been plotting joint attacks in Saudi Arabia and Yemen. The men, all Yemenis, were captured in the south-eastern province of Hadhramout. (dpa)
