A limousine belong to Vladimir Putin burst into flames after a tremendous explosion was heard along a Moscow street close to the FSB headquarters on March 29
The limousine was authentic. The place was nice, a few blocks from the FSB headquarters.
But there was no "tremendous explosion" - the car just burnt. Every house had its windows intact, the car itself had its windows intact while burning, etc.
Explanations: technical malfunction, passer-by with fire cubes and a lighter.
I probably don't know the correct term in English. It's a product for starting a fire in a wood-fired stove or campfire. A rectanglular block of wood fiber soaked in oil.
Your English was on point, and any outdoorsie types understood you. This is just one of those things that is called different names in different regions.
