UPS bomb from Yemen traveled on two passenger planes

One of the two bombs mailed from Yemen and found on cargo jets in Dubai and Britain travelled on two passenger jets in the Middle East, according to a spokesman for Qatar Airways.

The airline spokesman said a package containing explosives hidden in a printer cartridge arrived in Qatar Airways’ hub in Doha, on one of the carrier’s flights from the Yemeni capital Sana’a.

It was then shipped on a separate Qatar Airways plane to Dubai in the United Arab Emirates, where it was discovered by authorities late early on Friday. A second, similar package turned up in England’s East Midlands Airport…

The devices are similar to those developed by Ibrahim Hassan al Asiri, a Saudi jihadist who is thought to have designed a bomb smuggled on to a US-bound Christmas Day flight last year by Umar Farouk Abdulmutallab.
