The five children who were injured in a knife attack that left eight children dead at an east China elementary school last month are out of danger, doctors said Tuesday.

Four students had been moved out of intensive care to receive rehabilitation, while the fifth, Zhang Xuexin, was still in the ICU for observation, said Chen Xiaojie, deputy president of the No.1 Hospital of Nanping City, Fujian Province.

"Zhang, whose heartbeat stopped twice, can now read cartoon books with doctors," he said.

Former community doctor Zheng Minsheng has been arrested and charged with murder in connection with the March 23 attack outside the gate of the Nanping Experimental Elementary School.
