The White House earlier warned both Israel and the Iran-backed Hezbollah group against "escalation of any kind" following pager and walkie talkie explosions targeting Hezbollah members.

Israel was responsible for Tuesday's explosions, a source confirmed to ABC News, in which pagers detonated across Beirut and southern Lebanon. Walkie-talkies exploded on Wednesday. The strikes come after two consecutive days of explosions of pagers and walkie-talkie devices in Lebanon, which left at least 37 people dead.

Amid Israel’s effort to return tens of thousands of its citizens to their homes in the north, the Jewish state reportedly launched an operation to knock out Hezbollah’s infrastructure in Lebanon.
