Hezbollah admits Israel dealt a severe blow with exploding pagers and walkie talkies, but neither side seems to heed U.S. calls to avoid a wider war.

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

Hundreds of pagers carried by Hezbollah members blew up nearly simultaneously in an attack that tops a series of covert assassinations and cyber-attacks in the region.
