Customers flying to the United States from airports in Muslim-majority countries affected by the ban can once again bring their laptops and other electronic devices on board, the New York Times reports.
US authorities imposed the ban in March when intelligence said Islamic State was working to build a bomb inside a laptop.
"Having been around explosives all my life, the device as described to me had an amount of explosive on it that I just did not believe could destroy an airplane in flight", said Kelly, a retired Marine Corps general.
Homeland Security Secretary John Kelly said Wednesday that the temporary ban on large electronics in carry-on luggage on USA -bound global flights announced in March was set into motion after a similar explosive destroyed an aircraft during a test.
Passengers should be prepared to arrive even earlier to the airport than usual for worldwide flights inbound to the US - at least three hours in advance.
Father of Jordan attacker demands investigation into son's killing
Two Jordanians have been killed and an Israeli wounded in an incident next to Israel's embassy in Amman , BBC News reports. Two Jordanians later died, according to the agency and the news site Hala Akhbar, linked to the Jordanian military.
The threat has eased somewhat, the intelligence official said, in part due to the implementation of enhanced security measures.
The ban included 10 airports in North African and Middle Eastern countries.
Last week, the US government revised its security directive, which also include additional requirements that must be met within 120 days.
Officials released a statement to CBS News saying communication between the DHS and Transportation Security Agency led to the increase in airline safety. "Airlines were able to implement the necessary enhanced security measures because of the close coordination and extensive communication between aviation partners and DHS/TSA", the statement read.
The new measures may include asking passengers to present larger electronic devices for inspection and prove they can be powered on.
