You can use the bootstrap carrousel component: enter the description of the link here

In your case it would be something like:

var data = [{
  nombre: 'noticia1',
  fotos: [{id:0,foto:'https://ichef.bbci.co.uk/images/ic/720x405/p0517py6.jpg'},{id:1, foto:'https://images.mentalfloss.com/sites/default/files/styles/mf_image_16x9/public/549585-istock-909106260.jpg?itok=ds7LqH1N&resize=1100x1100'}]
  },
  {
  nombre: 'noticia2',
  fotos: [{id:3,foto:'https://images.mentalfloss.com/sites/default/files/styles/mf_image_16x9/public/549585-istock-909106260.jpg?itok=ds7LqH1N&resize=1100x1100'},{id:4,foto:'https://ichef.bbci.co.uk/images/ic/720x405/p0517py6.jpg'}]
  }
];

var app = new Vue({
  el:'#app',
  data: {
    noticias: data,
  }
});

.carousel{
  height: 200px;
  background-color: black;
  color: white;
}

        <span class="sr-only">Next</span>

Here you see that I create a div for each news and for each news we create a carousel with the photos that are being several "carousel-item", in your case it would create a tr for each news item and within the td the carousel, beware with the ids of the forward and backward controls, since I concatenate the array index to make them unique in the document.

I hope you serve, greetings!
