Unable to integrate with RSS feed service using JavaScript. Error "XMLHttpRequest for *** required Cross Origin Resource Sharing (CORS)"

I am working on a sharepoint online site. and i want to integrate with the following BBC RSS feed service to get the latest news items https://feeds.bbci.co.uk/news/uk/rss.xml. so i wrote the following javascript code:-

<div id="inserhere"></div>
<script src="https://***.sharepoint.com/Resources/jquery-1.11.3.js"></script>
<script>

$(function () { 
    //feed to parse
    var feed = "https://feeds.bbci.co.uk/news/uk/rss.xml";
    var html="<div ></div>";
    $.ajax(feed, {
        accepts:{
            xml:"application/rss+xml"
        },
        dataType:"xml",
        success:function(data) {


            $(data).find("item").each(function () { // or "item" or whatever suits your feed
            var el = $(this);
                    var nurl = el.find("link").text();
                    var ntitle = el.find("title").text();
                    var nurl2 = el.find("link").text();

html+="<div style='float: left;margin-left:9px' ><img style='height:90px;width:185px' src='"+nurl+"' alt='ntitle'><br/><span style='font-size:9px'><a target='_blank' href='"+nurl2+"'>"+ ntitle+"</a></span></div>";

            });


            $("#inserhere").after(html);
        }   
    });

});


</script>

but i got the following error inside my IE F12 tools:-
