All passengers flying into or out of the UK have been advised to ensure electronic devices in hand luggage are sufficiently charged to be turned on.

The Department for Transport (DfT) said there could be checks "on some routes into or out of the UK" but did not disclose which routes were involved.

The advice was already being applied on some flights from the UK to the US.

The government has not specified which routes will be subject to the new checks

The US announced new security measures last week, apparently in response to a terror threat.

American officials ordered some overseas airports with direct flights to the US to intensify screening of electronic devices.

This prompted Heathrow and Manchester airports to advise US-bound passengers to charge electronic devices to be carried as hand baggage before travelling.

British Airways said that customers flying to the United States faced being made to rebook if they were found in possession of an uncharged device.
