Remind me again, what do these riots have to do with cartoons?

From Fox News:

Protesters burned a KFC restaurant, three movie theaters and the offices of the main mobile phone company in the country. A Norwegian mobile phone company's offices were also ransacked. Gunfire was heard near the burning KFC, as police tried to clear people from a main street, witnesses said.

An 8-year-old boy died after being struck in the face by a bullet fired by a protester, police officer Shahid Khan said. A 25-year-old man was killed by an electric cable that was snapped by gunfire, said the man's cousin, Jehangir Khan.

The 8-year-old boy had something to do with cartoons? Little boys like cartoons, I guess.

Many Muslims regard any depiction of the prophet as blasphemous. They reject the newspapers' explanations that the cartoons have news value and represent free speech.

So they burned a KFC? I still don't understand. Could somebody explain this to me?
