During yesterday's unrest a commercial plane was destroyed, and the local courthouse and the residence of the provincial governor William Powi were burnt.
Local authorities say no one was injured when a Air Niugini Dash-8 aircraft was set on fire and destroyed on the airstrip at Mendi airport. The situation in the town is tense, the provincial capital having gone into lockdown overnight.
According to police, it was yesterday's national court ruling upholding Mr Powi's 2017 election which sparked the rampage.
