No refund cancellation policy and CoViD-19

My sincere apologies if this was already asked and answered before, I failed to find a similar question.

I had booked a flight earlier this year that had a non refundable cancellation policy. However, this flight was later cancelled due to CoViD-19 which meant the plane could not land in any of the countries on the itinerary.

I am wondering if I can receive a refund in this case.
