Hezbollah officials and Lebanon's state media say explosions went off in Beirut and multiple parts of Lebanon in an apparent second wave of detonations of electronic devices

At least 20 people have been killed and more than 450 wounded by a second wave of explosions from wireless communication devices in Lebanon, the country’s health ministry says.

Pagers, used every day by health care professionals, became a deadly weapon Tuesday as thousands of them simultaneously exploded in Lebanon.

Pagers used by hundreds of members of Hezbollah exploded almost simultaneously in Lebanon and Syria Tuesday, killing at least 12 people.

Thousands of people were injured across Lebanon and Syria on Tuesday by an Israeli covert operation that remotely detonated pagers, ABC News sources confirmed.

A devastating attack occurred in Lebanon and Syria when pagers, which are commonly used by Hezbollah members, were remotely detonated. The blasts killed 12 people and injured thousands. Experts believe the pagers contained small explosive devices that were likely installed during manufacturing and triggered by a remote signal.
