The Tanzanian government has banned 16 titles of a popular children’s book series from being used in schools for allegedly advocating LGBTQ rights.

The Diary of a Wimpy Kid series are said to violate the country’s traditions, customs and cultures.Education Minister Adolf Mkenda said the books endanger the quality of education for children.

Schools using the books will face disciplinary and legal measures, including having their registration revoked, the authorities said.

The banned books in the series are:

Diary of a Wimpy Kid: Rodrick Rules
Diary of a Wimpy Kid: The Last Straw,
Diary of a Wimpy Kid: The Ugly Truth
Diary of a Wimpy Kid: Cabin Fever.
Diary of a Wimpy Kid: The Third Wheel
Diary of a Wimpy Kid: Hard Luck
Diary of a Wimpy Kid: The Long Haul
Diary of a Wimpy Kid: Old School
Diary of a Wimpy Kid: Double Down
Diary of a Wimpy Kid: The Gateway.

“This is the first list, after we checked and verified that these books violate traditions and customs. The content in them are not good for the upbringing of Tanzanians. The review is ongoing,” said Prof Mkenda.

He urged parents to regularly check their children’s bags to ensure they are not using the books.
