All you have to see is that there was an attack and that multiple people were killed, and you know who did it - the point being that it's so unnecessary to ask, you'll do a double- or triple-take if I even momentarily suggest it was anyone other than who it obviously had to be:
Attackers raided a luxury hotel in Burkina Faso overnight, shooting some and taking others hostage in a siege that lasted hours and ended with 28 people dead.
