Hong Kong protests: foreign students start to leave as unrest shifts to universities
Danish university chief tells 36 students to return home as several protesters injured in violence
Dozens of foreign students have been urged to leave Hong Kong after another night of clashes left several people seriously injured.
A worker for the Food and Environmental Hygiene Department, struck by an object thrown by protesters earlier on Wednesday, was in critical condition, according to the government. A 15-year-old believed to have been hit in the head by a tear-gas canister has reportedly suffered a skull fracture.
