Italy earthquake leaves thousands homeless

Thousands of people have been left temporarily homeless after Italy's most powerful earthquake in 36 years.

People were pulled from the rubble in towns across central Italy and 20 were injured after buildings collapsed when Sunday's earthquake hit "like a bomb".

It struck at the heart of a region already struggling to rebuild after being devastated by a series of quakes, including one in August that left 298 people dead and two massive tremors four days ago.
