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.

As a reminder, this comes after Israel launched intensive overnight airstrikes in southern Lebanon, with the military saying its warplanes targeting Hezbollah rocket launchers. A barrage of rockets has been fired from Lebanon into northern Israel, the Israeli military says.
