The ceasefire between Israel and Hezbollah in Lebanon began on Wednesday morning, a day after Israel carried out its most intense wave of airstrikes in Beirut since the start of the conflict, killing at least 42 people across the country.

An Israeli strike smashed into a building in the southern suburbs of Beirut causing a huge explosion after a warning was issued by the Israeli military on X. The strike comes as cease-fire negotiations continue between Israel and Lebanon.

Israel was targeting a senior Hezbollah commander, but failed to kill him, one Israeli official said. Hezbollah officials said none of the group’s leaders were at the attack site.
