The moment of one of the explosions was captured by BBC World Service correspondent, Nafiseh Kohnavard.
The BBC’s Middle East correspondent, Hugo Bachega, reported from a car as he described scenes of chaos in the Dahieh district.
Israel’s military says it attacked Hezbollah’s “central headquarters” in the Dahieh neighbourhood, a Hezbollah stronghold.
