An American woman accused of killing 2 of her children fights extradition in a London court

An American woman accused of killing her two youngest children in Colorado last December told her 11-year-old daughter who survived the attack that God made her do it, a prosecutor said in a London court.

An American woman accused of killing her two youngest children in Colorado last December told her 11-year-old daughter who survived the attack that God made her do it, a prosecutor said in a London court.

The girl begged for her life after Kimberlee Singler stabbed her and -- despite the child's plea for mercy -- cut her again, prosecutor Joel Smith said.

The harrowing details came as Singler fights extradition to the United States in Westminster Magistrates' Court.

Singler denies attacking her children and is concerned her daughter's statement to police was coerced, defense attorney Edward Fitzgerald said.

Singler should not be extradited from the United Kingdom because if she's convicted of first-degree murder in the U.S. state of Colorado, where the killings took place, she would face life without parole -- a sentence that violates European human rights law, Fitzgerald argued on Friday.

Singler, 36, is charged with two counts of first-degree murder in the shooting and stabbings of her 9-year-old daughter and 7-year-old son, and one count of attempted murder for harming her older daughter.

She faces additional counts because the children were under the age of 12, along with an additional count of assault.
