Tourists on open-top tour bus pelted with snowballs in Rome

Tourists got a little more than they bargained for onboard an open-top bus in Rome.

As wintry weather hit the Eternal City some locals found it was an irresistible target for snowballs.

Tourists on the top of the bus which was heading towards the Colosseum were left unable to defend themselves as it was hit from all angles.

Elsewhere in the Italian capital the military had to be deployed as the city struggled to cope with the freezing temperatures.
