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.

Officials in Lebanon reportedly have banned pagers and walkie-talkies from being brought onboard planes departing Beirut following explosions targeting Hezbollah.

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

The attack came hours after Hezbollah fired 140 rockets at northern Israel and follows this week's deadly explosions of pagers and walkie-talkies carried by Hezbollah members.

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.
