The Saudi government has arrested more than 700 suspected al-Qaeda-linked militants this year, officials announced Wednesday.
The Interior Ministry says some of these suspected terrorists were planning separate attacks against the kingdom's oil and other economic installations.

The detainees had planned a car bomb attack against one of the kingdom's oil installations, officials said. They belonged to "cells" which planned to revive "criminal activities" in the kingdom, and their leaders were based outside the country.
Of the individuals originally detained, more than 500 remain in custody. The rest were released because there was no proof linking them to the terror network, the official Saudi Press Agency reported.
It is the largest number of detainees ever held by Saudi authorities.
According to police, one of the suspects had a message from Ayman al-Zawahri - al-Qaeda's No. 2 leader - which police discovered. It is not known if the message was a letter or some other form of communication.
