A popular Tunisian children's magazine is to be prosecuted for telling its young readers how to make a petrol bomb, officials said on Tuesday. The latest edition of "Qaws Quzah", Arabic for "Rainbow", featured a piece about the history of petrol bombs in its "Knowledge Corner", including detailed instructions and a diagram.

"It is an improvised weapon that is often used in riots and acts of sabotage because it is easy to make and use," the article read.

The magazine, read for decades in Tunisia by boys and girls aged between five and 15, has no political orientation.
