The official said the suspects were planning to carry out attacks in Mecca, according to information gathered during interrogations Sunday. He did not identify any intended targets.
In 1979, some 1,200 Sunni Muslim extremists seized the Grand Mosque in Mecca, but the revolt was crushed.
Saudi authorities have cracked down on suspected militants since the May 12 bombings, which were seen as attacks not just against foreigners but also the ruling Saudi royal family for its close ties to the US.
