A plot to fly planes into religious shrines in Iraq has been foiled.
Al Qaeda was reportedly planning to hijack flights from Iraqi airports and crash into holy sites, including the domed shrine in Najaf that's considered one of the holiest Shiite sites in the world.
Iraqi and U.S. security officials worked together to bust the plot. Two suspects are in custody.
Security has been stepped up at Iraq's airports. The airport in Najaf remains closed while the investigation continues.
"If there had been a dangerous act, all airports would be closed. the Najaf airport will be re-opened shortly. And because of being very close to the city, the Najaf airport's re-opening was delayed," Iraqi Transport Minister Amir Abdul-Jabbar said.
Prime Minister Nouri al-Maliki has ordered background checks on all pilots flying in and out of local airports.
