Four Iranian nationals will stand trial in Saudi Arabia over allegations of involvement in acts threatening�the kingdom�s security, a report says.

The website of the Arab News on Friday quoted a report by theSaudi Gazette as saying that the four Iranians, including an alleged spy, will stand trial in the near future.

�The Bureau of Investigation and Public Prosecution is in the process of referring the case of four Iranian nationals implicated in national security issues to the Special Criminal Court pending their trial,� said the report, adding that the four were arrested in 2013 and 2014.

It said one of the four was arrested in March 2013, when Saudi authorities claimed to have busted an�espionage cell, which included 24 Saudi citizens and three expatriates from Iran, Lebanon and Turkey. It said the other three Iranians, who were arrested in 2014, are still under investigation.

The report would not elaborate on the details of the petition against the Iranians, but said a fifth Iranian national, who was arrested in 2008 and is currently serving a 13-year sentence, had recruited and made travel arrangements for �a number of Saudi young men to go to Tehran, and coordinating with other parties to send them to conflict zones,� including in Afghanistan.

The report comes days after Saudi Arabia severed diplomatic relations with Iran in response to angry demonstrations in front of its diplomatic posts in two Iranian cities of Tehran and Mashhad. Some people attacked the Saudi premises.

The protests were held in the wake of Riyadh�s announcement on January 2 that prominent cleric Sheikh Nimr al-Nimr had been executed. Nimr was arrested in 2012 in Eastern Province.
