Tufts graduate student injured in attack in China park

A doctoral student at Tufts University is one of four U.S. college instructors recovering in China after the park attack.

Family members say David Zabner was one of four Americans who had traveled from Iowa when they were targeted in the northeastern city of Jilin.

The State Department said one of the teachers accidentally bumped into the man, who then turned around and attacked them with a knife.

This man is currently in custody.

All instructors were taken to hospital and are expected to be OK.
