The U.S. is planning a security overhaul at airports amid fears that joint terror groups are developing undetectable bombs that can be implanted inside terrorists.
U.S. intelligence suggests that the “non-metallic” devices would not be found by current airport security techniques.
The Department of Homeland Security has ordered increased security at overseas airports linked to America after gathering intelligence about a joint plot between Al Qaida and the al-Nusra Front.
The groups had allegedly been testing the “stealth bomb” device during the Syrian war, according to an official who spoke to the Daily Mail on the condition of anonymity.
Al-Nusra was behind the 2009 failed underwear bombing on a Detroit flight.
“We remain concerned about the capability of some of these elements to develop weapons that could be thwarted by our current security systems,” Homeland Security said a statement.
Officials say there is no imminent threat.
“The Department of Homeland Security is regularly reviewing our security procedures to adapt to the threat that we — that is faced by our transportation system, as advisories are required to adequately inform the traveling public, we’ll make those announcements,” the statement said.
Specific steps taken at airports have not been disclosed. So far there has been no change to what travelers can take on flights.
"We will work to ensure these necessary steps pose as few disruptions to travelers as possible," Homeland Security Secretary Jeh Johnson said in a statement. "We are sharing recent and relevant information with our foreign allies and are consulting the aviation industry."
