Secretary of State Antony Blinken traveled to Egypt for fresh talks on an Israel-Hamas cease-fire, as tensions with Hezbollah persist at the Israel-Lebanon border in the wake of the shocking explosions of wireless devices.

Walkie-talkies and other devices exploded suddenly Wednesday at the site of a funeral for three Hezbollah members and a child killed by exploding pagers the day before. Lebanon’s health ministry says at least nine people were killed and 300 were wounded.

Walkie-talkies were detonated across Lebanon Wednesday in a second straight day of deadly explosions. CBS News New York's Dick Brennan reports.

Israel launched a series of strikes on Hezbollah targets Thursday as the war against the Lebanon-based group widened in the wake of two consecutive days of deadly explosions triggered in wireless devices.

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

Hezbollah war grows as the two sides trade new fire, Hezbollah's leader accuses Israel of crossing "red lines."

At around 3:30 in the afternoon on Tuesday, the pagers across Lebanon began beeping, delivering a message from Hezbollah leadership to their operatives through a chorus of chimes, melodies, and buzzes.
