Tighter Security for flights to US

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".

Transport Secretary Patrick McLoughlin confirmed the measures, saying they were being taken to protect the public.

While he would not specify what steps would be involved, he ruled out "significant disruption" to passengers.

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."
