Some of the 11 children who were knifed during an attack in a kindergarten in China's northwestern Shaanxi province have been moved out of the intensive care unit.

Officials say the incident in Hanzhong is the latest in a series of copycat attacks on schools across the country in recent weeks.

The attacks have terrified parents and prompted local authorities to step up security.

Officials said some of the suspected attackers were suffering from mental illness, as in Thursday's incident in which seven children and two adults were killed.
