US: Restrictions on US airline travellers were eased slightly yesterday, but homeland security secretary Michael Chertoff said that the threat of an attack on airliners remained.
The Transportation and Security Administration (TSA) said on its website that it would allow passengers to bring up to 4 ounces (1.6 ml) of non-prescription liquid medication on board, including pain-relievers and cough medicine. It also said that it would allow glucose gel and other medicines for low blood-sugar treatments for diabetics.
The TSA had barred all liquids, except baby formula and breast milk from flights last week because of an alleged plot to bring down airliners flying from the UK to the US.
Yesterday the TSA also said that it would require all passengers travelling on domestic and international flights to remove their shoes for screening.
But while the US moved quickly last week to tighten security, Mr Chertoff told CBS's news programme Face the Nation that he knew of no suspects in the US connected with the plot uncovered in Britain.
"As we speak right now, we've not found any indication of active planning in the US or plans to conduct operations within the US," he said. "Nothing so far."
British police have arrested about two dozen people in connection with the plot.
