One man has been sentenced to death and 19 others have been jailed for up to 25 years by a Saudi court in connection with the 2004 armed attack on the US consulate in Jeddah in which five employees were killed.
The official Saudi Press Agency said a further 35 suspects linked to the consulate storming, blamed on al Qaida, will face court hearings this week.
The report gave no further details on the man given the death penalty or when the execution could be carried out.
The attack on the heavily guarded compound came amid a series of attacks by al Qaida-linked militants in response to crackdowns across Saudi Arabia. Gunmen killed five locally hired consulate workers, and four attackers were fatally wounded in the three-hour battle.
