Ananova:

Parents are fuming after education chiefs introduced a school music book that included a traditional Spanish song about smoking cannabis.

La Cucaracha - popular in the Mexican civil war - is about soldiers, dubbed cockroaches which refuse to march because they have no marijuana to smoke.

But a scandal has broken out in Bosnia and Herzegovina after a new educational book distributed to primary schools gave a full translation of the lyrics.

Parents have demanded the Federal Ministry of Education, which approved the book by Refik Hodzic, recall it immediately and have slammed the decision to send it out to schools as "ridiculous".

Mum Sanya Bolic, 38, from Sarajevo, whose nine year-old son told her about the book, said: "I could not believe it when I found out about this.

"The last thing I want my son learning about in primary school is drugs. Whoever made the ridiculous decision to put this book in schools must have been out of their head themselves."
