HONG KONG (AP) — Tens of thousands of Hong Kongers lined up to vote Sunday, joining hundreds of thousands of others who cast electronic ballots in the first three days of an unofficial referendum on democratic reform that Beijing has blasted as a farce.

Tensions have soared in Hong Kong over how much say residents of the former British colony can have in choosing their next leader, who’s currently hand-picked by a 1,200-member committee of mostly pro-Beijing elites.
