There's suggestions a sabotage of a delivery from Taiwan lead to exploding pagers injuring thousands in Lebanon.

At least nine people are dead - including a child - and close to 3000 injured after Hezbollah-owned pagers blew up simultaneously.

Hezbollah is blaming Israel.

Deakin University terrorism expert Greg Barton says Hezbollah ordered 5000 pagers from Taiwan about five months ago to avoid Israeli surveillance.

"Presumably, there was circuitry added with explosives, coded so when a wireless message went out with a certain code, it triggered the devices."
