ADELAIDE, AUSTALIA (AP) -- A school principal in Australia says a high school teacher who assigned her class to plan a terrorist attack was not trying to promote terrorism.

The Year 10 students at Kalgoorlie-Boulder Community High School in the state of Western Australia were given the assignment last week in a class on contemporary conflict and terrorism.

Principal Terry Martino said he withdrew the assignment as soon as he heard of it.

He says the teacher "is relatively inexperienced" and called the assignment "well-intentioned but misguided."

Martino says the highly regarded teacher just made a mistake and understands the topic was inappropriate.

The school declined to identify the teacher, citing her privacy, and her name also was not given in the newspaper report.
