A collision on a highway in Italy caused an extraordinary blast that killed at least two people
and left at least 70 others injured.
It happened near the city of Bologna. Police say a tanker truck carrying liquefied petroleum gas
was involved in a traffic accident.
The initial collision caused a fire, but shortly after the entire truck exploded,
sending flames across all lanes of the highway and into the air
