The beam of light is in a different spot than the explosion
The explosion itself is an IED, maybe a Vehicle Borne IED which would explain why the boom was shifted to the right of the beam of light.
It could have been a DEW from an aircraft above
The explosion is not that big but a truckload of explosives is quite possible.
The clouds indicate a rainy overcast high humidity day which explains why the shock wave was visible. It caused water vapor to condense into droplets.
Not sure why it is being compared to Beiruit because it is tiny in comparison.
