Iraqi Prime Minister Haider al-Abadi says his country's intelligence sources have warned of ISIL plans to carry out attacks on subway systems in the United States and France, Press TV reported.
On Thursday, Abadi said captive ISIL Takfiri militants have told Iraqi intelligence agents of the alleged plot.
The comments were made on the sidelines of a United Nations General Assembly meeting in New York.
The Iraqi premier said he was informed of the purported plot by officials in Baghdad, noting that the plan involves French and US nationals who had joined the ISIL militants in Iraq.
"Today, while I'm here I'm receiving accurate reports from Baghdad that there were arrests of a few elements and there were networks from inside Iraq to have attacks...on metros of Paris and US," Abadi said, adding, "They are not Iraqis. Some of them are French, some of them are Americans. But they are in Iraq."
Abadi stated that the plot has not been thwarted yet and that Washington has already been alerted.
The Iraqi army has been fighting ISIL terrorists. The militants currently control large areas of Syria's east and north. They sent their Takfiri militants into Iraq in June, seizing large parts of land along the border between Syria and Iraq.
ISIL terrorists have been carrying out horrific acts of violence, including public decapitations and crucifixions.
Western leaders have been voicing concern over the expansion of ISIL's terror operations beyond the Middle East. They are concerned that citizens who have joined the Takfiri group will engage in terrorist activities after returning home.
