Hezbollah walkie-talkies exploded across Lebanon on Wednesday in a second round of electronic communications device detonations just one day after 12 people were killed and thousands were injured in similar explosions Tuesday.

Lebanese media reported several explosions in Beirut, Lebanon, and Dahiyeh, a Hezbollah-dominated suburb of the capital. Pictures and videos posted on social media showed large fires resulting from the explosions, which were apparently hidden in different devices than the pagers used in Tuesday’s attack.
