There are two ways you could go in:
1) Modify viewtopic.php to show the news post above the replies with a clear divider.
2) Create your own page with your own code to fetch replies.I'd personally be in favour of 1 if you don't know much PHP, but if you know your way around PHP 2 should definately be doable too.
I'm afraid 1 would not work, as the news pages cannot simply be posted into the forums. So, I have to work it in reverse by finding a way to subsume -- or embed -- the forum topic into the existing Web page containing the news story.
