The Islamic State of Iraq and the Levant (ISIL) extremist group  has banned the study of philosophy and chemistry in schools in the northern Syrian city of Raqqa and established an “Islamic curriculum” for students, the Syrian Observatory for Human Rights (SOHR) said on Friday.
The ISIL asked teachers and school directors to “prepare an Islamic education system in the schools of Raqqa”, which would be reviewed by a board of education appointed by ISIL. 
The “Islamic experts” belonging to the ISIL decided to exclude chemistry and philosophy from the educational programme because “they do not fit in with the laws of god”, the SOHR reported.
The ISIL promised adequate wages  to teachers and principals after the government of Syrian President Bashar Al Assad stopped paying their salaries following the takeover of Raqqa by Islamist rebels.
ISIL militants closed several schools in the province, which had an educational programme consistent with the Syrian regime or with rival Islamic brigades which controlled Raqqa before them.
The militants on Thursday killed nine members of rival Islamic groups in the Syrian town of Akhtarin in northern Aleppo province. They also stoned to death one of their militants, a Tunisian, after he raped a young displaced girl from Deir Al Zor city.
The ISIL controls Raqqa and large parts of Deir Al Zor, where various armed groups have sworn allegiance to it.
In June, the militants declared the setting up of an ‘Islamic caliphate’ in the territories under their control in Syria and Iraq.
