An Indonesian kindergarten apologised Monday after images of its pint-sized students marching in niqab veils and carrying cardboard cutouts of assault rifles sparked outrage.
Organisers were left red-faced after a torrent of criticism suggested the ISIS-style outfits promoted jihadist violence in a country that has long struggled with terrorist attacks.
The group of about 15 students were taking part in a parade for Indonesia's independence day Friday near the country's second-biggest city Surabaya.
The Kartika kindergarten, which is located inside a military complex in Probolinggo town, said the costumes were resurrected from storage to save parents the cost of buying new ones.
It denied that the gun replicas and full-body veils promoted extremism.
"I never meant to teach violence to my students," said school principal Suhartatik, who like many Indonesians goes by one name.
"We only used the props that we already had to cut costs for parents. I deeply apologise."
The costumes had been used in previous parades to teach students about the prophet Muhammad's faith and beliefs, she added.
But the principal's explanation was met with derision on Indonesian social media.
"Nobody carried assault rifles in the prophet's time - is this teacher that clueless about history or was she just trying to dodge the blame?" one user posted on Twitter.
Another tweeted: "Obviously the seeds of ISIS are being nurtured early on."
Indonesian parliamentary speaker Bambang Soesatyo also lashed out at what he dubbed a "very concerning case".
"Parents and teachers should protect children from damaging their way of thinking," he told news site Detik.
Parade organisers said they were embarrassed for failing to notice the provocative outfits.
"I really apologise -- I did not check beforehand," said chief organiser Supini.
"This was supposed to be a cultural parade."
The incident came as Indonesia looks to promote itself as host of the 18th Asian Games, the world's biggest multi-sport tournament after the Olympics.
Indonesia has endured a spate of deadly terrorist violence in recent years.
The 17,000 island archipelago, which has the world's biggest Muslim population, suffered its worst attack in a decade in May after IS-inspired suicide bombers attacked several churches.
Indonesia's deadliest terror attack was the 2002 Bali bombing which killed over 200 people.
