He said that the attack includes the U.S. embassies, attacks in the Middle East, but he didn’t provide specific information about the plot.

Pompeo made the new comments during a White House press briefing after telling Fox News on Thursday the government didn’t know when or where the attack would take place.

“We don’t know exactly which day it would have been executed, but it was very clear: Qassem Soleimani himself was plotting a broad, large-scale attack against American interests, and those attacks were imminent,” Pompeo told CBS News White House correspondent Paula Reid.

President Trump addressed the drone strike on Iran’s top general during a rally with supporters in Toledo, Ohio, on Thursday night.

“Soleimani was actively planning new attacks, and he was looking very seriously at our embassies and not just the embassy in Baghdad, but we stopped him, and we stopped him quickly, and we stopped him cold,” the president said without offering any evidence to support his claim.

Sources told CBS News that members of Congress were not told during a briefing by administration officials earlier this week about any imminent threats to U.S. embassies, CBS News chief congressional correspondent Nancy Cordes reports.

This move was initiated to possibly shoot down Iranian drones as intelligence mounted about a threat of an imminent attack against US targets, two US officials tell CNN.

The alert reflects the heightened tensions between the US and Iran in the wake of last week’s US drone strike that killed a top Iranian general, Qasem Soleimani.

US officials have claimed the strike against the general was carried out to prevent an “imminent” attack in the region that would have put American lives at risk, but have so far declined to provide details about the intelligence.

US intelligence also has observed Iran moving military equipment, including drones and ballistic missiles, over the last several days.

US officials said the movement may be an Iranian effort to secure its weapons from a potential US strike, or put them in positions to launch their own attacks.

“There were indications that we needed to monitor the threats” even more closely than is already being done, one of the US officials said, referring to Monday night’s state of heightened alert.

The second official described it as “all Patriot batteries and forces in the area on high alert” against an “imminent attack threat.”
