The United States is not aware of any specific threat to the U.S. homeland from Islamic State militants, the Department of Homeland Security said on Friday after Britain raised its international terrorism threat level.
Islamic State militants and their supporters, however, “have demonstrated the intent and capability to target American citizens overseas,” Homeland Security Secretary Jeh Johnson said in a statement. He noted DHS has taken steps over the summer to strengthen security at overseas airports with direct flights to the United States.
Johnson said he has spoken to UK Home Secretary Theresa May about Britain’s decision to raise its terrorism alert to the second-highest level. It is the first time since mid-2011 that Britain has been placed on this high of an alert level.
White House spokesman Josh Earnest said there was no plan to raise the U.S. threat assessment level.
“This is a threat that the United States has been focused on. We’ve been coordinating closely with our allies, both the Brits, but others in Europe, about countering this threat and mitigating it,” he said at a news briefing.
