Saudi Arabia 88 terrorists - The Muslim country has arrested a total of 88 individuals on suspicion of scheming terrorist attacks both in the kingdom and abroad, the interior ministry declared on Tuesday.

According to several Saudi Arabia 88 terrorists reports, the interior ministry said that the arrested men were under surveillance for several months before they were taken into custody, and "were on the verge of carrying out operations."

More than half of the detained individuals are Saudi natives while three men have been identified to be from Yemen, and the other one's nationality is still being determined, Police said.

A few of the Saudi Arabia 88 terrorists suspects had connections to the Islamic State group operating in Iraq and Syria, to the Nursa Front group in Syria r to the al Qaeda branch in Yemen, spokesman to the Ministry Major General Mansour Turki, told Reuters following a news conference.

"They showed their support to the organizations in Syria and Iraq and also in Yemen, and they wanted to get involved in their activities. Some of them tried to get ... instructions of what he should do, how he should act inside the kingdom," Turki said.

Saudi Arabia 88 terrorists correspondents said the kingdom has increased its security amid Islamic State's offensive in Syria and Iraq.

Turki said some of the Saudi Arabia 88 terrorists suspects had plotted to implement assassinations inside the kingdom and had communicated with alleged terrorists abroad. One suspect is said to have even penned Friday sermons for extremist members abroad.

The spokesman didn't elaborate on the plots, but revealed that 59 of the detainees had been jailed previously for similar offenses.

Saudi Arabia has banned its citizens earlier this year from fighting for groups abroad amid concerns that those citizens would eventually pose a threat to the kingdom's stability.

Saudi King Abdullah cautioned on Saturday that terrorism would soon advance to Europe and the United States unless it was quickly handled in the Middle East.

The Saudi Arabia 88 terrorists captivity is a part of the country's nationwide security operation, CNN has learned.
