Does this grouping include Jabat Al-Nusra?

Hay'at Tahrir al-Sham, formerly Jabhat Fatah al-Sham, formerly Jabhat al-Nusra, formerly Al-Qaeda in Syria. Each time they got a new name, they had absorbed some minor groups that shared their jihadi ideology.

Any videos of said attack?

Yes. It is part of an Amaq propaganda video and I guess you won't find those anyway on youtube due to strict guidelines for ISIS propaganda. There are snippets on twitter though. As you can see they are using a quintuple arrangement of what is believed to be 73mm rocket assisted grenades for the SPG-9 recoilless gun. I believe those deliver quite a punch:
