Good photo from within the last 30 minutes.
Fire on the train is spreading from fuel car to fuel car and the steel and concrete of the bridge will be vastly compromised.
You can clearly see 2 spans if the road bridge have been dropped with no sign of cratering on the spans themselves - must be shaped charges rather than a missile attack - interesting the other lane wasn’t dropped.
Catching the train as it passed would suggest they charges were either set off remotely as it passed.
