Inside Yemen after parcel bomb discovery
Security checks are being stepped up on air freight coming in to the UK, with shipments graded according to risk.
The announcement from the British Department of Transport is the latest move to upgrade security since parcel bombs were intercepted on US-bound cargo flights.
The plot has been blamed on al-Qaeda in the Arabian Peninsula, a group which the government in Yemen is struggling to contain.
Jeremy Bowen reports from the capital, Sanaa.
