Symfony - How can I omit the first item in a twig template's loop?

There is more concise version of what Robert suggested:

{% for item in news[1:] %}

You can use slice filter which works like array_slice() function in PHP.

{% for item in news[1, news.length -1 ] %}

put this in your loop to omit first news

{% if loop.index0 > 0 %}
 {# display your news #}
{% endif %}
