Manchester Arena Bombing

Three Islamists - Khuram Shazad Butt, Rachid Redouane and Youssef Zaghba - drive into pedestrians on London Bridge then run amok in the nearby Borough Market area in fake suicide bomb vests, stabbing people at random before police fatally shoot all three. Eight innocents die, including two Australians, and 48 are injured.
