There are also fears that more explosive devices may still be at large. This has begun to question the safety of freight transportation as well as the difficulty of detecting explosive material.

The two ink cartridge bombs found at East Midlands Airport on Friday have originated in Yemen and were found only after a tip-off from Saudi intelligence.

Yemeni police have released student Hanan al-Samawi, 22, who was arrested on suspicion of sending the packages. A shipping agent, however said she was not the same person who signed the shipping documents.
