Weird. Both those youtube videos that were posted regarding this had blowing shofars in the background...which suggests to me that it’s fake.
I’d think there’d be news reports all over Israel talking about mysterious blowing shofars.
If it occurred on Rosh HaShana shofars blowing would not be a big deal. Even during the month of Elul that leads up to Rosh HaShanah Jews are also blowing them.
Shofar, so good.
