British police said parts of Glasgow airport in Scotland had been evacuated after the discovery of a suspicious item. The security alert came after two parcels sent from Yemen and containing explosives were uncovered last Thursday in Britain and Dubai on cargo planes en route to the US. It also followed a Greek parcel bomb plot that has seen packages mailed to European leaders and foreign embassies in Athens. Greece has said the plot has no link to international terror. Western governments have since imposed new restrictions on freight in the wake of the plot and Yemen has scrambled to contain the fallout by announcing exceptional security measures on all freight leaving Yemeni airports.
