The examples did. But you see explosions from time to time in places where propane is stored and the heat is extreme, with the addition of dry conditions, a static charge.

So, the car this morning was “smoking.” The plan was to heat up the tanks and cause them to explode to create more damage.

I'm sure that they would have exploded and caused some damage and perhaps a fire that could hurt a lot a people, but AFAIK a compressed gas cylinder containing a gas that normally must be mixed with air to burn will not explode with anywhere near the power of a high explosive.

When a container of gas explodes upon heating, the explosion to due to the increased pressure in the tank. So at the moment of rupture of the tank, the gas is not yet even burning.
