Print a value from database twig drupal 8 bootstrap carousel

I am trying to pass a value from database to render photo url in bootstrap carousel. I hope this i right approach. I do not know how to filter / render only value without div wrapper (please see output)

paragraph–carousel.html.twig >

{% set classes = ['carousel', 'slide'] %}
<div{{ attributes.addClass(classes) }} data-ride="carousel" data-interval="{{ interval }}" data-pause="{{ pause }}" data-wrap="{{ wrap }}">
    {% if indicators %}
        {{ indicators }}
    {% endif %}
    <div class="carousel-inner" role="listbox">
        {% for field_images_demo in content %}
            {% set slide_classes = ['item', start_index == loop.index0 ? 'active'] %}
            <div{{ attributes.addClass(slide_classes) }}>
                <img src="{{ field_images_demo|clean_class }}"/>
                {% if field_image_demo.title or field_image_demo.description %}
                    <div class="carousel-caption">
                        {% if field_images_demo.title %}
                            <h3>{{ field_images_demo.title }}</h3>
                        {% endif %}
                        {% if field_image_demo.description %}
                            <p>{{ field_image_demo.description }}</p>
                        {% endif %}
                    </div>
                {% endif %}
            </div>
        {% endfor %}
    </div>
    {% if controls %}
        {{ controls.left }}
        {{ controls.right }}
    {% endif %}
</div>
