Students and staff from the University of Papua New Guinea's medical faculty are refusing to return to class until the government can guarantee their safety, following a rampage by soldiers last Sunday.
Thousands marched from the University's Waigani campus to parliament in Port Moresby on Thursday and presented the government with a petition demanding action in response to the attack which left dozens of staff and students injured.
The Vice President of the University's Student Representative Council, Nou Vada, says a list of demands by the students includes reimbursements for laptops and books destroyed in the attack, compensation for the victims, and greater security.
"The petition requested constant special police presence at the Taurama campus 24 hours a day before the students and the staff can return to work."
The defence force and police have launched separate investigations into the incident and Nou Vada says he understands at least three soldiers have been arrested so far.
