Two senior Hong Kong officials have urged anti-extradition protesters to avoid politicising children as the new school years gets under way on Monday.
Writing on his blog, Chief Secretary Matthew Cheung said it was extremely irresponsible for some people to advocate a boycott of classes, as schools are for studying, not politics.
His comments come as organisers say thousands of pupils have agreed to stay away from school to press home the five demands of the anti-extradition movement, including the full withdrawal of the government's now stalled extradition bill and a public inquiry.
Meanwhile Financial Secretary Paul Chan said bullying at schools would not be tolerated, amid concerns that the children of police officers will be targeted.
He warned that such bullying would see "the seed of hatred" planted even deeper in the community.
