Stockholm - A German woman charged with beating two small children to death in Sweden in March this year should serve a life term or be confined to a closed psychiatric institution, the prosecution said Monday.

In her summing up, prosecutor Frieda Gummesson told the court in the central city of Vasteras there could be no doubt that the 32-year- old student, who comes from Hanover, was guilty of the March 17 murder.

Jealousy had been the motive in the murder of the three-year-old boy and his one-year-old sister in the town of Arboga, Gummesson said.

The children's mother, who lives with the accused's former lover, was seriously hurt in the attack.

The accused has denied the charges. She told the court she had been in Arboga at the time of the murders to visit archaeological sites.

Legal experts said the outcome of the trial remained open, noting that there was no DNA evidence linking the accused, who was extradited to Sweden in April, to the crime. (dpa)
