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

Lebanon blamed Israel for attacks on Hezbollah that killed 37 and wounded around 3,000, wreaking havoc on the militant group.

The deadly Hezbollah-pager explosions are causing mounting distrust, with some Lebanon residents abandoning their electronic devices.

Israeli public broadcaster Kan said on Friday around 150 rockets were fired from Lebanon across the border. Israeli ambulance service said there were no immediate reports of casualties. Lebanon's Hezbollah announced on Friday they launched seven separate attacks on Israeli targets with Katyusha rockets.

The attacks in southern Lebanon follow others on Hezbollah rocket launchers and infrastructure, after Hezbollah vowed to respond to detonations of pagers and radios.

Walkie-talkies and solar equipment exploded in Beirut and other parts of Lebanon on Wednesday in an apparent second wave of attacks targeting devices a day after pagers used by Hezbollah blew up, state media and officials for the militant group said.
