If the parade was "filmed completely since the beginning, there will be no misunderstanding". he said.
Local media reported that Education and Culture Minister Muhajir Effendy said the parade was misinterpreted and the staff of the school, located inside a local military command, had no intention to instil radicalism in children.
It contained many elements, he said, including symbols of Muslims who struggled for Indonesia's independence and the red and white of Indonesia's national flag.
"It was recorded when these veiled children carried only replica guns," he told reporters. "In fact, there were themes raised by these children, namely the struggle of Islam. Until finally this piece of video spread on social media and was very biased." However, the principal of the school apologised.
Nurrizal said the provincial police's cyber unit is helping to track down the video uploader.
