Four Iranians including an alleged spy will stand trial in Saudi Arabia, local media reported on Friday, as a diplomatic crisis festers between the regional rivals.
The Arab News daily reported that three of the suspects are alleged “terrorists” while another is accused of espionage.
It gave no details of the accusations.
The Saudi Gazette said they were arrested in 2013 and 2014, but did not identify them.
A fifth Iranian is already serving a 13-year jail term following his conviction for recruiting young Saudis to fight in neighbouring countries, the newspapers said.
The reports come after tensions escalated between Riyadh and Tehran.
