airport security tightened over \'bomb fears\'
S. Department of Homeland Security Secretary Jeh Johnson said he had asked officials to \"implement enhanced security measures at certain overseas airports with direct flights to the United States in the coming days \".
However, he declined to say which airports would be affected.
A statement issued by the Department of Homeland Security said: \"We are sharing the latest relevant information with our foreign allies and consulting the aviation industry.
\"These communications are an important part of our commitment to provide our security partners with situational awareness about the current environment and protecting the tourism public.
Transportation Minister Patrick McLoughlin said additional security measures are not expected to cause \"significant\" disruption to flights.
He told Sky News: \"I want to reassure the travel public that we have one of the world\'s toughest security regimes with the United States.
\"It is important that we take these measures to protect the tourism public, and when we get the information, the public is confident to take the right steps.
\"There will be additional security checks, but they will be done in the events that people have already experienced and I hope there will be no major delays.
But British aviation safety expert Philip Baum said that strengthening security checks inevitably means that the queue time and waiting time for boarding at British airports will be extended.
\"This means that the number of random searches will increase,\" he said: \"a secondary search and an increase in the number of passengers who request to take off their shoes, if passengers take certain flights, all passengers may be asked to take off their shoes. \".
\"It makes sense that if we take longer to do the inspection, people will have to take longer to queue up for boarding.
