The United States has announced that it will start profiling US-bound passengers to determine who should get extra screening.
The measures will replace mandatory enhanced screening of all travellers from 14 nations, brought in after the failed attack on a flight in December, the BBC reports.
Under the new measures, passengers would be picked out for further screening depending on how closely they matched intelligence on potential terrorist threats.
The screening will take into account nationality, age and recently visited countries.
The new strategy results from a review ordered by President Obama.
The measures will apply to US citizens, as well as foreigners travelling to America.
