• More explosions were reported across Lebanon on Wednesday.
• Reports indicated that hand-held radios blew up.
• The latest incidents follow deadly blasts Tuesday when pagers belonging to Hezbollah exploded.

Hand-held radios exploded across Lebanon on Wednesday, according to multiple reports, potentially signaling a second wave of coordinated attacks targeting personal devices in the Middle Eastern country.

The official broadcaster of the Iran-backed Hezbollah militant group, Al-Manar, reported a wave of explosions from wireless devices across Lebanon, according to local and international media.

The Lebanese Red Cross said dozens of ambulance teams were responding to explosions nationwide. Several people are dead and hundreds more injured, according to the Associated Press, with the number of casualties likely to rise as the scope of the carnage becomes more clear.

The reported explosions follow a similar incident Tuesday in which scores of pagers used by Hezbollah members simultaneously detonated across Lebanon. At least a dozen people were killed, and thousands more were left injured by the blasts.

A security service source told Reuters that the devices that detonated on Wednesday, hand-held radios or walkie-talkies, were purchased several months ago, around the same time as the pagers that exploded on Tuesday.

One video circulating around social media on Wednesday purportedly shows an explosion at a funeral for Hezbollah members who were killed the day prior.

Hezbollah and Lebanon both blamed the Tuesday explosions on Israel, which has not claimed responsibility. Israel has a long history of clandestine operations beyond its borders, targeting Iran and its regional proxy network.

The apparent attack came shortly after Israel indicated that it would increase military pressure on Hezbollah so that people in the north of the country who have been displaced by months of fighting between the two bitter enemies could return home.

Hezbollah has vowed revenge for the explosions this week, threatening to plunge the embattled region into even more violence.
