Figure or Div, which should I use?

I’m designing a news site. I use thumbnails of news on the homepage. Should I use the div or figure tag for them?

Sample figure,

<a href="/news_url"> <figure>   <img src="news.jpg" alt="news">   <figcaption>News headline</figcaption> </figure></a> 

Sample div,

<a href="/news_url"> <div>   <img src="news.jpg" alt="news"> </div>   <span>News headline</span> </a> 

Does it make any difference in terms of SEO?
