Nineteen people have been killed and more than 50 injured in the suspected terror attack on the Manchester Arena. The explosion happened just after the end of a pop concert by the US singer Ariana Grande, who is popular among children and teenagers.
Witnesses said that the attack appeared to involve the use of a nail bomb. Nail bombs (often also including nuts, bolts and ballbearings) are used to increase the destructive power of explosives, as the shrapnel increases the bomb’s ability to wound its victims.
The Manchester police are working on the assumption of terrorism. If so, it would be the worst act of terrorism in Britain since the "7/7 bombings" in 2005 on London Transport, which killed 52 people.
