Pro-democracy rallies expanded to new parts of Hong Kong in the wee hours of China's National Day, a holiday that looked set to bring crowds and tensions to a peak and increase the chances for a confrontation. Earlier on Tuesday, protest organizers called on Leung Chun-ying, the city's chief executive, to resign and said protests would spread if he didn't respond to their demands by midnight. That deadline passed with no sign of a response from Mr. Leung.
