DSP Rajkumar Silwal of the Airport Security Office confirmed that the fire had broken out in the tyres during landing and was extinguished with the help of fire engines. 'The situation is now normal,' he said, adding that the runway had been temporarily closed for a technical inspection. The aircraft, which was reportedly also carrying some human remains and cargo, came to a halt on the main runway after the incident, disrupting international flight operations. No international arrivals or departures were possible for a period as the aircraft remained on the runway before being towed to a taxiway. Authorities said an investigation into the cause of the fire was under way.
