Saudi TV channel Al-Hadath reported that around 500 members of Lebanon’s Hezbollah lost their eyesight following yesterday’s massive attack that caused pagers to explode throughout Lebanon and Syria.

The report did not elaborate further.

Hezbollah chief Hassan Nasrallah is set to make an address tomorrow Thursday – a statement by the group said today.

Nasrallah will speak at 5:00 pm (1400 GMT) on Thursday in a speech addressing "the latest developments", the statement said.

Hundreds of pagers used by Hezbollah members exploded across Lebanon Tuesday, killing at least nine people and wounding around 2,800 in blasts.

There was no immediate comment from the “Israeli” military on the wave of explosions, which came just hours after “Israel” announced it was broadening the aims of the war.

The blasts "killed nine people, including a girl", Lebanese Health Minister Firass Abiad said.

He added that about "2,800 people were injured, about 200 of them critically".

A senior Lebanese security source told Reuters that the “Israeli” spy agency planted explosives inside 5,000 pagers imported months before by Hezbollah.

The unprecedented operation was months in the making; the Lebanese group ordered 5,000 pagers from Taiwanese company Gold Apollo, which were brought into the country earlier this year, believed to be somewhere around March/February – sometime after Hezbollah’s Secretary-General Hasan Nasrallah warned members of the group to stop using cellphones for security purposes.

The low-tech communication method was an attempt to evade “Israeli” intelligence and location-tracking.

"The Mossad injected a board inside of the device that has explosive material that receives a code. It's very hard to detect it through any means. Even with any device or scanner," another source told Reuters.

The pagers then exploded after a coded message was sent to the devices, the blast occurred 10 seconds after the initial beep so Hezbollah fighters could hold the device close to their face to read the message – per Hebrew media.
