According to Travel Radar, the A350 -the registration is still unknown- was being towed to the Tarmac when it collided with the Boeing 777-300 (B-KPD).
In the next images it is possible to see the damage caused on both Cathay Pacific aircraft. The Airbus A350 suffered damage on the right-side winglet, meanwhile the Boeing 777 is damaged on the left horizontal stabiliser.
According to the same source, the airport Ground Controller received a call at 12:30 (local time) alerting them to the incident that occurred on Taxiway J. The taxiway in question is now being used for storage, due to the low demand caused by COVID-19.
