A year 7 girl from a western Sydney high school has reportedly been punished by the NSW Education Department after she said she liked ISIL and praised the recent Paris attacks and a suicide bombing in Lebanon.

Birrong Girls High School was contacted about the student's comments by concerned Muslim parents yesterday, The Daily Telegraph reports .

A fellow student's mother told the newspaper that on Monday the year 7 girl said she liked ISIL and was happy about what happened in Beirut and Paris.

"She doesn't even feel pity for the people killed which is really sad," the woman said.

More than 40 people were killed in twin suicide attacks in the Lebanese capital the day before the attacks in Paris.

The student who made the comments was reportedly given either a warning or a three-day suspension.

Muslim community leader Jamal Daoud confirmed that "Christian and Shia girls clashed with an extremist girl who expressed happiness at what happened in Lebanon and Paris".
