Facebook introduced group video chats for Messenger on Android, iOS and via Messenger.com on desktop.
Vice president of messaging products David Marcus made the announcement Monday, saying that users who tap the video camera icon within a group chat can send notifications to other participants, who can choose to join, adding that individual members of the group chat can also be called:

(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.8";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
