Tighter security for flights to US

The unspecified measures will be put into place in some airports with
direct US flights
Security is being tightened at airports with direct flights into the
US - including some in the UK - in response to US warnings of a
"credible threat".

The UK transport department confirmed airport security was being stepped up.
Neither UK nor US authorities specified what new measures would be
involved but the UK said most passengers should not experience
"significant disruption".

It comes amid US media reports that al-Qaeda affiliates in Syria and
Yemen are developing bombs to smuggle on planes.
A US Department of Homeland Security (DHS) official said the changes
were a response to a "real time" and "credible" threat but it could
not comment on specific intelligence matters.
"Aviation remains an attractive target to global terrorists, who are
consistently looking for ways to circumvent our aviation security
measures.

"As always, DHS continues to adjust security measures to fit an ever
evolving threat environment.
"Information about specific enhancements and locations are sensitive
as we do not wish to divulge information about specific layers of
security to those who would do us harm."
What changes will we see?
by Richard Westcott, Transport Correspondent
Longer queues are a possibility
The UK government isn't giving any details about what these security
changes actually are, but they haven't ruled out longer queues at
security.

The statement from the department for transport merely says that the
majority of passengers should not experience significant disruption.
What we do know is that all of the old rules remain in place. So you
will still have to put liquids into separate, see-through bags, take
your laptop out of your bag, take off your belt and maybe your shoes
before going through security.

It's also not clear whether these changes will affect every airport,
and whether they are limited to flights to and from the United States,
which has prompted this move.
The actual terrorism threat level remains the same, at substantial.
That's the middle of the five threat levels and means that an attack
is a strong possibility.
Necessary steps
DHS Secretary Jeh Johnson said in a statement: "We will work to
ensure these necessary steps pose as few disruptions to travellers as
possible,"
"We are sharing recent and relevant information with our foreign
allies and are consulting the aviation industry."

The changes will be made in the "upcoming days", the department added.
In a statement, the UK Department for Transport said the country had
"taken the decision to step up some of our aviation security
measures".
He added: "For obvious reasons we will not be commenting in detail on
those changes. The majority of passengers should not experience
significant disruption."

An anonymous US official told Reuters news agency that European
airports would be taking the extra precautions.
Law enforcement and security officials sources told the news agency
that Western authorities were discussing security measures that
included extra scrutiny of US-bound passengers' electronics and
footwear, among other measures.

Al-Nusra Front, al-Qaeda's affiliate in Syria, and Yemen-based
al-Qaeda in the Arabian Peninsula are believed to be working together
to try to develop explosives that could avoid detection by current
airport scanners, US media report.
