Three people working at Baghdad International Airport were detained by Iraqi authorities late Thursday on suspicion of having leaked detailed information of Iranian General Qasem Soleimani’s movements to the Americans, according to two sources with direct knowledge of the investigation.
The two sources spoke with CNN on the condition of anonymity due to security concerns.
The three detained workers are Iraqi nationals, the sources said.
Iraqi authorities launched an investigation this week into the circumstances surrounding the US strike that killed Soleimani and a top Iraqi paramilitary figure.
Investigators are pursuing what they suspect is a "spy network" believed to have leaked information and details of Soleimani's movements to the Americans.
The Iraqi investigators believe that the suspected leaked information was key to the US operation that killed Soleimani and Abu Mahdi al-Muhandis, deputy head of the Popular Mobilization Units (PMU) — an umbrella group of Iranian backed Shia paramilitary groups.
The investigation, headed by Faleh al-Fayadh, Iraq's national security adviser and head of the PMU, has focused on questioning security personnel at Baghdad International Airport, where the strike took place last Friday.
Soleimani flew to Baghdad international Airport from Damascus, according to the sources.
A parallel investigation is being conducted by Syrian authorities at the Damascus International Airport, the sources said, adding the Iraqi and Syrian investigators are communicating with each other.
