The Taliban government has removed books written by women from the university teaching system in Afghanistan as part of a new ban which has also outlawed the teaching of human rights and sexual harassment, BBC reported.

Some 140 books by women - including titles like "Safety in the Chemical Laboratory" - were among 680 books found to be of "concern" due to "anti-Sharia and Taliban policies".

The universities were further told they were no longer allowed to teach 18 subjects, with a Taliban official saying they were "in conflict with the principles of Sharia and the system's policy".

The decree is the latest in a series of restrictions which the Taliban have brought in since returning to power four years ago, according to BBC.
