A 55-year-old Italian nurse was arrested on suspicion of murdering 13 elderly patients in the intensive care ward where she had worked for decades, police said on Thursday (March 31).

The "hospital ward killer", as police have called her, administered lethal doses of a blood-thinning drug into her victims' intravenous drips. Twelve died of internal bleeding and one of cardiac arrest, police said.
