A Facebook post from the boyfriend of a young woman stabbed to death Tuesday in Australia was going viral as local law enforcement investigated the attack by a French national who allegedly shouted “Allahu Akbar” repeatedly during the deadly assault. The attack at a Queensland hostel left Mia Ayliffe-Chung dead at the scene.

A 30-year-old British man was also attacked at the Shelly’s Backpackers hostel and hospitalized in critical condition Tuesday evening, the Independent reported. The Guardian reported that Ayliffe-Chung, 21, was visiting Australia from Derbyshire in the U.K. and was reportedly days into a three-month working holiday.
