As + Present Participle/Gerund?

[Sydelle]

For my grammar assignment I have to analyze 3 grammatical issues from a random contemporary article. Unfortunately, I have encountered a problem - how could I explain the two following examples (in red)? I searched the internet but could not find anything that would be very useful. Perhaps someone has some idea or could direct me to a grammar book, where I could find an explanation? Thank you :)

Associated Press also reported the opposition as declaring it had formed its own government.

"Neither Russia, nor your humble servant, nor Russian officials have any links whatsoever to these events," the RIA news agency quoted him as saying.

Can you see the red parts? I must be color blind. Ok, now I see them.

Associated Press also reported the opposition as declaring it had formed its own government

These questions will get you closer:

Do you understand this sentence?
Do you know what 'as' do there?

Ok, I will help more.

as = preposition, used to describe the quality of someone or something

Definition of as preposition from Cambridge Dictionary Online: Free English Dictionary and Thesaurus

preposition followed by -ing: What is it? Gerund.

One further small point to aid comprehension (of the example rather than the principle). 'Your humble servant' means 'I/me' (depending on how it fits in its sentence).

Thank you :) I found some articles on the internet which said preposition + ing = gerund, but 'as' was never listed among those prepositiosn, which is why I was not sure :)
