Two former Twitter employees and a former employee of the Saudi royal family faced charges in the US of spying on critics of Saudi Arabia in exchange for payment.

Saudi citizen Ali Alzabarah and US citizen Ahmad Abouammo, who used to work for Twitter, and were accused on Wednesday of working for the Kingdom of Saudi Arabia without registering as foreign agents.

The two former employees were alleged to have taken private user data and of prominent Saudi royal family critics and passed it on to the Saudi government with the help of Ahmed Almutairi, who acted as a go-between.

The targeted accounts included a news personality and a prominent government critic with over 1 million followers on the social media platform.

Twitter thanks the FBI but the Saudis remain silent

Microblogging site Twitter thanked the FBI and US Justice Department, which carried out the investigation.

"We recognize the lengths bad actors will go to try and undermine our service" said the company in a statement. "We understand the incredible risks faced by many who use Twitter to share their perspectives with the world and to hold those in power accountable."

The Saudi embassy in the US did not immediately respond to a request for comment.

According to Human Rights Watch Middle East researcher Adam Coogle, Twitter is the main platform for Saudis to express their views and about a third of the country's 30 million people are active users.

The complaint marked the first time that the oil-rich Gulf state and Washington ally has been accused of spying in the US, news agency AP reported.

The allegations come soon after the one-year anniversary ofthe murder of Jamal Khashoggi, the prominent Saudi critic who was killed at the Saudi consulate in Istanbul.
