DUBAI, March 21 (Reuters) - New restrictions on passengers carrying electronics on U.S. flights will be in place for nearly seven months, an Emirates spokeswoman said on Tuesday.

The Department of Homeland Security (DHS) will require passengers travelling from 10 Middle East airports, including Emirates' Dubai hub, to stow electronic devices larger than a mobile phone with their checked baggage on all flights to the U.S. from the end of the week.

An Emirates spokeswoman confirmed the airline was subject to the "new security directive issued by the Transportation Security Administration."

Devices such as tablets, portable DVD players, laptops and cameras will have to be checked under the directive. Medical devices will be excluded.

"The directive comes into effect on 25 March 2017 and is valid until 14 October 2017," the Emirates spokeswoman said in an emailed statement. "It is applicable to all U.S.-bound passengers from Dubai International Airport, whether originating or transiting through."

Earlier, Reuters reported the restrictions are in response to unspecified terror threats. The DHS said the procedures would "remain in place until the threat changes" and did not rule out expanding to other airports if circumstances changed.
