no need or do need "the" here?

Hi,

why no "the"?

"...over how to react the country's removal last week of U.N. seals from its main unranium enrichment facility and (no "the") resumption of research on nuclear fuel." - not an exact quote

also, when quoting a newspaper article in part or in the whole, do I have to mention the source (i.e. where the article is from - the name of the newspaper) when using it to ask questions in a forum like this?
