Usually with groups like Al Qaeda, they take responsibility right away, they don’t hold back in their “Celebration” either they would take responsibility online or on video..its been too many hours if they were involved they would have already taken credit for it..but I do wonder if the China knife attack which killed 29 people, if there might be a connection here, I wouldnt be surprised
The only thing I consider is a terrorist attack on China would get a no holds barred response. The Chinese don’t have political correctness to keep them in check. The Chinese officials will finance Muslim terrorists and let them do their thing on others but they sure don’t want them around.
My guess is Chinese aircraft parts chickens finally coming home to roost.
