An Egyptian education official is under investigation for burning library books from a school suspected of belonging to the Muslim Brotherhood group, a government-declared terrorist organization.

Bothaina Kishk, an Education Ministry official from Cairo's Giza district, is defending her decision, saying Wednesday that the books incited violence and were "corrupting" children.

She approved and oversaw the burning of some 80 books in the school courtyard earlier this month.

The school has been under government control along with more than 100 others as part of a crackdown on associations linked to the Brotherhood, which was declared a terrorist organization following the 2013 military ouster of Islamist President Mohammed Morsi.

Pictures of Kishk with others burning the books caused an outcry in Egypt, prompting an official investigation into her actions.
