An Israeli military leader has issued a new threat to Lebanon, saying it is time for the country "to suffer as well." Tensions are escalating between Israel and Lebanon, after Hezbollah suffered two unprecedented attacks in which pagers and walkie-talkies used by the militant group exploded near-simultaneously on Tuesday and Wednesday.

A key Hezbollah commander and his chain of command were killed in an Israeli strike in Beirut on Friday, according to the Israel Defense Forces, as tensions continue to rise along the Israel-Lebanon border.

Hassan Nasrallah refused to say when or how Hezbollah would take revenge. As he spoke, Israeli fighter jets swooped low over Beirut.
