Stop playing video in iframe when modal is closed

Question

I have a play image with text 'Watch video', when clicked would open up a bootstrap modal window to play the video i put in. I've got the moday view to work. The problem I'm having with this is when I play the video and exit the screen while it is being played, the video continues to play in the background. If I click on the Watch Video link again, it would play the video from where it stopped off previously.

I need to have the video stop when the modal window is closed. It needs to then play the video from the start the next time I click the "Watch video" link. I'm still new to this and am not sure how to do this. Anyone know how I can achieve this?

<div class="col-md-12 f-play" data-toggle="modal" data-target="#myModal">
    <img class="f-play-image" src="images/play.svg" data-target="#myModal" data-video-fullscreen="">Watch video
</div>

<div id="myModal" class="modal fade" role="dialog" tabindex='-1'>
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-body">
                <div class="embed-responsive embed-responsive-16by9">
                    <iframe class="embed-responsive-item" src="https://www.youtube.com/embed/7pvci1hwAx8?" allowfullscreen="" width="640" height="360" frameborder="0"></iframe>
                 </div>
             </div>
             <div class="modal-footer">
                 <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
             </div>

        </div>
    </div>
</div>

I managed to get it to work with the link that @Leo provided. But it was slow as it reloaded the frame everytime the link was clicked. Tried @guillesalazar solution from Twitter Bootstrap Modal stop Youtube video and it worked perfectly. This was the solution I used.

$("#myModal").on('hidden.bs.modal', function (e) {
    $("#myModal iframe").attr("src", $("#myModal iframe").attr("src"));
});
