Suicide bomber at Nigerian school kills 47 and injures 79

There are obviously many different ways to kill a large number of people.  This attack is deadlier than any attack in the US.  From the WSJ:

A suicide bomber on Monday blew himself up during a school assembly in northeastern Nigeria, killing at least 47 people and showing how an Islamist insurgency is apparently drawing young, radical and educated people to its ranks. 

The explosion took place shortly after a morning assembly began at the Government Senior Science Secondary School in Potiskum in Nigeria’s northeastern Yobe state, said Nigeria Police Spokesman Emmanuel Ojukwu. He reported 79 injured, in addition to 47 dead. . . .
