On distinction, Finucane explained that the carriers of the pagers and walkie-talkies would have to be "lawful targets, either on the basis of their status as fighters in an organized armed group that is party to a conflict with the attacker, or due to their direct participation in hostilities."

The device explosions appeared to be the culmination of a monthslong operation by Israel to target as many Hezbollah members as possible all at once.

Multiple explosions occurred at the site of a funeral for three Hezbollah members and a child killed by exploding pagers the day before, according to Associated Press journalists at the scene.

Lebanese health officials ordered the public Tuesday to avoid using handheld communication devices after members of the militant group Hezbollah's pagers reportedly exploded throughout the country.

Lebanese officials say more handheld devices exploded a day after thousands of pagers carried by Hezbollah members blew up in an attack blamed on Israel.
