KABUL, Afghanistan (AP) — A mother who tried to stop her son from carrying out a suicide bomb attack triggered an explosion in the family's home in southern Afghanistan that killed the would-be bomber, his mother and three siblings, police said Monday.

The would-be bomber had been studying at a madrassa, or religious school, in Pakistan, and when he returned to his home in Uruzgan province over the weekend announced that he planned to carry out a suicide attack, Interior Ministry spokesman Zemeri Bashary said.

Surviving family members told police that the suicide vest exploded during a struggle between the mother and her son, said Juma Gul Himat, Uruzgan's police chief. The man's brother and two sisters were also killed.

Family members said the would-be bomber gave his family $3,600 before telling them he intended to carry out the attack, Himat said.

Bashary said the explosion happened on Sunday, but Himat said it occurred on Monday morning. It was not clear why the two accounts differed.

That's one reason why you don't pay ransom to the Taliban when they kidnap your countrymen.
Here's another reason.
