Dozens of people were injured Tuesday when handheld pagers exploded in the suburbs of Beirut and other parts of Lebanon, according to Lebanese state media.

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

BEIRUT — Walkie-talkies exploded in Beirut and other parts of Lebanon on Wednesday in a second wave of attacks targeting devices a day after pagers used by Hezbollah blew up, state media and officials for the militant group said. At least 20 people were killed and more than 450 wounded in the second wave, the Health Ministry said.
