I've been learning about indirect speech in German. I think I understand the concept pretty well, but I have come across an article with this paragraph (it's a translation from another language into English, sorry if there are mistakes):
There are a lot of theories about the Earth - the Earth is round, the Earth is flat, the Earth is carried on the back of four elephants... Recently, however, the flat Earth theory has been gaining popularity. Among the supporters of this concept is an Italian couple who tried to reach the "edge of the world", but got lost on the way and ended up in quarantine. This was reported by the Italian newspaper La Repubblica.
I am not sure if this would be considered an indirect speech. The sentences themselves don't have a reporting verb, but the "reported" at the end of the paragraph threw me off. Should I, therefore, use Konjunktiv?
I tried to look for similar structures online and found this example, where they used "sollen":
Haushalte mit geringem Einkommen sollen im Juni einen einmaligen Heizkostenzuschuss bekommen. Das berichtete Tagesschau.de.
Could someone please explain this to me?
