Border Closure Question

I had travel booked to a city Sunday-Tuesday. I was planning on taking a cross-border bus, but on Saturday afternoon the border was closed indefinitely. On the advice of locals that it wouldn’t reopen until Wednesday (which turned out to be true), I booked a flight for Sunday morning.

I couldn’t find any indicators that either of these events would be covered by the insurance. Not holding my breath, but just want to make sure I’m not leaving money on the table.
