Islamic State terrorists have allegedly plotted attacks on New York and Paris subways, Iraqi Prime Minister Haider al-Abadi said Thursday at the United Nations, according to multiple sources. While U.S. intelligence has not confirmed such ISIS threats, New York Gov. Andrew Cuomo said he was handling the statement “with the utmost precaution.”

"Our administration has been coordinating at a high level with local, state and federal partners,” Cuomo said. “I want to assure the people of New York that we are monitoring these reports closely and are in close communication with officials in Washington.”

Al-Abadi made the remarks about the terrorist plots on New York and Paris on the sidelines of a U.N. General Assembly meeting of world leaders at the U.N. headquarters in New York City. He said Iraqi intelligence in Baghdad had captured several ISIS militants who confessed during interviews that Islamic State recruits in the U.S. and France had planned to target subway systems in Paris and New York. Al-Abadi said he heard about the threat Thursday and had informed U.S. security officials.

"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 U.S.," al-Abadi said during the U.N. meeting. "They are not Iraqis. Some of them are French, some of them are Americans. But they are in Iraq."

U.S. National Security Council spokeswoman Caitlin Hayden said the plots have not been confirmed but that the council would review “any information from our Iraqi partners.” She said the security council takes “any threat seriously.”

The U.N. Security Council passed a resolution Wednesday requiring intelligence agencies to share information with each other. The resolution was introduced by President Barack Obama.
