Dozens of people have been killed by Israeli strikes in Lebanon, including 20 who died after a strike flattened a multi-story residential building in central Beirut overnight, according to Lebanese officials.

Lebanese officials say Israeli airstrikes have killed at least 20 people and injured dozens in central Beirut, as the once-rare attacks on the heart of Lebanon’s capital continue without warning.

The Israel Defense Forces continued its intense airstrike and ground campaigns in Gaza -- particularly in the north of the strip -- and in Lebanon, with Israeli attacks on targets nationwide including in the capital Beirut.
