A group of six women and thirteen children with alleged links to ISIL (the Islamic State militant group) has returned to Australia after travelling from a Syrian refugee camp, landing in Sydney and Melbourne on Tuesday. Australian Federal Police made no arrests on arrival but confirmed that inquiries are ongoing, while Home Affairs Minister Tony Burke warned that anyone found to have engaged in criminal activity would face prosecution. The return — the second such group to arrive this month — has drawn public anger and a heavy police presence at Melbourne airport, where a scuffle reportedly broke out, reflecting the broader tension faced by Western governments over how to handle citizens who joined or accompanied ISIL roughly a decade ago.
