Four staff from a US university have been stabbed in a park in northeast China.
Video on social media showed blood-stained people lying on the ground and being put into ambulances.
Iowa politician Adam Zabner said his brother was among the victims and the group had been visiting a temple in Beishan Park, Jilin City.
“I spoke to David… he is recovering from his injuries and doing well. My family is incredibly grateful that David survived this attack,” said Mr Zabner.
The group from Iowa’s Cornell College were on a teaching exchange programme with Jilin’s Beihua university.
Cornell’s president, Jonathan Bran, said the four instructors were with a faculty member from the university when they were stabbed.
A wanted poster of the suspect has been released, but the motive is currently unclear.
China’s foreign ministry said it appeared to be a random incident.
The US State Department said it was aware of a “stabbing incident” and was monitoring the situation.
