Explosives implanted in devices before they arrived, Lebanon's UN mission says

United Nations: A preliminary investigation by Lebanese authorities into the communications devices that exploded in Lebanon this week found that they were implanted with explosives before arriving in Lebanon, according to a letter by the Lebanese mission to the United Nations that was seen by Reuters.

The authorities also determined the devices, which included pagers and hand-held radios, were detonated by sending electronic messages to the devices, says the letter, sent to the UN Security Council.
