The Special Criminal Court in Riyadh sentenced to death on Wednesday seven terrorists for carrying out the 2014 al-Dalwah attack in al-Ahsa in eastern Saudi Arabia.
Three others were sentenced to 25 years in jail.
Ten out of the 12 convicts appeared in court for their sentencing.
In November 2014, three militants opened fire at dozens of people in the village, killing eight people.
The court ordered the death penalties, including execution and crucifixion, to the first four defendants and the death penalty for defendants No. 6, 7 and 12. The defendants No. 8, 10 and 11 were sentenced to 25-year jail terms, starting from the date of their detention.
The court also ruled to confiscate weapons, ammunition and bullets seized from the defendants.
The defendants were convicted of the armed attack on Al-Rida Mosque in Al-Ahsa in November 2014, when one of them deliberately killed a citizen and stole a car for use in the terrorist attack.
Another defendant was convicted of attempting to buy a ton of explosive nitrate from Yemen.
Investigations revealed the participation of some of the defendants who attended the Specialized Criminal Court in Riyadh, in killing two security men during the armed confrontation in the Al-Moalemeen neighborhood in the city of Buraidah.
They were also found to be planning to target some preachers, security men and military airports, and seeking to secure materials used in the manufacture of explosives.
